Why We Finally Made the Switch From Propane (And Why It Took Us Three Years to Admit It)
The propane smell woke us up at 2 AM outside Flagstaff in November 2023. Not a leak, the lingering odor from cooking dinner six hours earlier, trapped in the fifth wheel because we had sealed everything tight against the cold. We cracked a window, froze for the rest of the night, and in the morning said the same thing we had been saying since 2021: we should really look into an RV induction cooktop.
But we did not.
We had been full-timing since 2018, and propane worked. It worked when we were boondocking in Utah. It worked when we were plugged in at state parks. It worked even when it did not work particularly well, which was most of the time. The burners took forever to boil water. The oven heated unevenly and turned the entire rig into a sauna by the time dinner was ready. Refilling the tanks was a hassle we had learned to tolerate, the way you tolerate a lot of things in RV life that are part of the deal.
The real reason we resisted switching to an RV induction cooktop was simpler than any of that: we did not want to admit we had been wrong about propane for three years. We had defended it to other RVers who raved about induction. We had convinced ourselves that the smell, the heat, the refill runs, the uneven cooking — all of it was the cost of having a real stove in a rig. Switching felt like admitting defeat.
Then we spent a month in the desert outside Quartzsite in January 2024, and the propane situation became impossible to ignore. We were cooking outside half the time because firing up the stove turned the fifth wheel into an oven. The other half of the time, we were dealing with burners that would not stay lit in the wind or took twenty minutes to bring a pot of pasta water to a boil. One night, we gave up and ate cold sandwiches because we could not face another round with the cooktop.
That was the moment. Not dramatic, not dangerous. tired.
We ordered a portable induction cooktop from Costco for sixty-nine bucks, plugged it in the next day, and boiled water in four minutes. Four minutes. We stood there staring at the pot like we had witnessed a magic trick. The cooktop stayed cool to the touch. The rig did not heat up. There was no smell, no waiting for burners to catch, no adjusting the flame every thirty seconds because the wind shifted.
We have been using induction ever since, and the only thing we regret is waiting three years to try it.
The Safety Thing Nobody Talks About Until Something Goes Wrong
We never had a propane accident, but we knew people who did. A friend’s regulator failed at a campground in Tennessee and filled their Class A with gas before they smelled it and got out. Another couple we met in New Mexico had a burner malfunction and nearly started a fire on their cooktop. These were not careless people. They were experienced RVers who did everything right, and propane still found a way to become dangerous.
Induction does not have that problem. The cooktop itself does not get hot. The pan does, but the surface around it stays cool enough to touch seconds after you remove the pot. There is no open flame, no gas line, no risk of carbon monoxide building up if your ventilation is not perfect. We have cooked with the windows closed in a rainstorm and never once worried about what we were breathing. According to the Consumer Product Safety Commission, carbon monoxide from fuel-burning appliances is a serious concern in enclosed spaces, which makes electric cooking options worth considering for safety-conscious RVers.
The myth that induction is somehow dangerous because it uses electricity is nonsense. Your microwave pulls more power and nobody loses sleep over that. The cooktop shuts off automatically if there is no pan on the burner, if the pan is removed, or if it overheats. Propane does not do any of that. It keeps burning until you remember to turn it off.
What Actually Happens to Your Battery and Power System When You Cook With an RV Induction Cooktop
The first time we used the portable induction cooktop off our inverter, we watched the battery monitor like it was going to explode. The Duxtop unit we bought pulls 1,800 watts at full power, and our system was not exactly built for that kind of draw. We had a 2,000-watt inverter and a 200 amp-hour lithium battery bank, which technically could handle it, but we had no idea how long we could actually cook before the batteries hit the floor.
Turns out, not long. We made breakfast — scrambled eggs and toast — and burned through about 15 percent of our battery capacity in twenty minutes. That was on shore power at a campground, so it did not matter, but it made us realize that cooking off-grid with induction was going to require some changes.
We upgraded to a 3,000-watt pure sine wave inverter and added another 100 amp-hour battery to the bank. That gave us enough capacity to cook a full meal without panicking about the voltage drop. On a sunny day with our 400 watts of solar running, we can cook lunch and barely notice the dent. On a cloudy day or at night, we are more careful. We do not run the cooktop on high unless we need to, and we avoid cooking two things back-to-back without letting the batteries recover.
The math is straightforward once you understand it. An 1,800-watt cooktop pulls about 150 amps from a 12-volt battery system. If you cook for thirty minutes at full power, you are using roughly 75 amp-hours. That is a lot. A 200 amp-hour battery bank can handle one or maybe two meals before you need to recharge. A 300 amp-hour bank gives you more breathing room, especially if you are not cooking at full blast every time.
We also learned that not all RV induction cooktop options are created equal. Some models let you dial in the exact wattage, which is incredibly useful when you are trying to conserve power. Others have settings like low, medium, and high, which makes it harder to predict how much juice you are actually using. The Duxtop has numbered settings from 1 to 10, and we have learned that setting 6 is usually enough for most cooking without maxing out the draw.
If you are plugged into shore power, none of this matters. The cooktop pulls from the campground’s 30 or 50-amp service, and your batteries stay topped off. But if you are boondocking or running on solar, you need to plan your power budget around cooking the same way you plan around running the air conditioner or charging laptops. We have written more about managing power while boondocking if you want to dive deeper into electrical system planning.
Portable vs. Built-In: The RV Induction Cooktop Installation Choice That Surprised Us
We went with the portable unit, and we have never regretted it. The sixty-nine-dollar Costco cooktop sits on our counter, plugs into a standard outlet, and does everything we need. When we are not using it, we slide it into a cabinet. When we are cooking outside, we bring it out to the picnic table. It is flexible in a way a built-in unit never could be.
Built-in induction cooktops look cleaner, and if we were renovating the entire kitchen, we might consider one. But the installation cost is a different game. The True Induction built-in models we looked at run around two hundred seventy-five bucks, and that does not include the labor to cut the countertop and wire it in. For RVers who are handy, that might not be a big deal. For us, it was a deal-breaker. The portable unit was plug-and-play, and it worked the first time we turned it on.
The only downside to portable is storage. It takes up counter space when you are using it, and cabinet space when you are not. If your RV kitchen is already tight, that might be a problem. But we would rather deal with that than commit to a permanent installation we might want to change later.
The Cookware Reckoning (And Why Your Cast Iron Might Not Work)
We thought our cast iron skillet would be perfect for induction. Cast iron is magnetic, right? It should work.
It did not.
The bottom of the pan was warped enough that it did not sit flat on the cooktop, and the induction burner kept shutting off because it could not detect consistent contact. We tried our stainless steel pots next, and half of them worked while the other half did nothing. One pot heated up fine. Another pot, identical except for the brand, would not even register on the cooktop.
The test is simple: if a refrigerator magnet sticks firmly to the bottom of the pan, it will work on induction. If the magnet barely clings or slides off, forget it. We went through every pot and pan we owned, and only about half made the cut. The rest went into a box we donated at the next town with a thrift store.
We replaced most of our cookware with a set from Caraway, which is not cheap but heats evenly and has flat bottoms that actually make contact with the burner. We also kept one Lodge cast iron skillet that we bought new, because the bottom is perfectly flat and it works like a dream on induction. The old warped skillet we had been using for years? Gone. Induction does not tolerate that kind of imperfection.
The cost of replacing cookware is something nobody warns you about when you switch to induction. We spent about two hundred bucks on new pots and pans, which felt like a lot at the time but made sense once we realized how much better the cooking experience was with the right equipment. Cheap pans with uneven bottoms are frustrating on any cooktop, but induction will flat-out refuse to work with them.
The Power Draw Reality: What Our Electrical System Actually Does
Most RV electrical systems are not built for induction cooking, and that becomes obvious the first time you try to run the cooktop and the air conditioner at the same time. Our fifth wheel has a 50-amp service, which gives us more headroom than a 30-amp rig, but even we have tripped breakers when we got careless.
The issue is that RV circuits are typically rated for 15 or 20 amps per outlet, which translates to 1,800 or 2,400 watts. An induction cooktop for RV use maxes out at 1,800 watts, so it is already pushing the limit. Add a hair dryer, a space heater, or the microwave, and you are going to flip a breaker. We learned that the hard way one morning when we tried to make coffee and toast at the same time the cooktop was running. The whole circuit went dark, and we had to reset the breaker from outside in the rain.
Now we are more careful. We do not run high-draw appliances while the cooktop is on. We check the battery monitor before we start cooking off-grid. And we have learned to cook smarter — using lower heat settings when possible, turning the burner off a minute or two before the food is done and letting residual heat finish the job. Induction is efficient, but it still demands respect for your electrical system’s limits.
Six Months In: What Actually Changed About How We Cook and Live
The biggest surprise was not the speed or the safety. It was how much cooler the rig stayed. We used to avoid cooking during the hottest part of the day because the propane stove would turn the fifth wheel into a furnace. Now we cook whenever we want, and the temperature inside barely budges. That alone has changed how we live in the summer.
The frustration we still deal with is power management. Cooking off-grid requires planning in a way propane never did. We have to check the weather forecast to know if we will have enough solar input to recharge the batteries after a big meal. On cloudy days, we sometimes run the generator for an hour to top off the bank before we start dinner. It is not a deal-breaker, but it is a trade-off we did not fully appreciate until we were living with it.
If you are full-timing and spend most of your time plugged into shore power, switch to an RV induction cooktop immediately. You will wonder why you waited. If you are boondocking more than half the time and your battery bank is under 300 amp-hours, wait until you can afford to upgrade your electrical system first. Your RV induction cooktop is worth it, but only if your rig can actually support it without making you miserable.
We are six months in, and we have not touched the propane cooktop since that morning in Quartzsite. The tanks are still full. We will probably disconnect them entirely next time we are near a service center, because we have no reason to keep them anymore. That sixty-nine-dollar portable RV induction cooktop from Costco turned out to be one of the best upgrades we have made to the rig, and the only thing we regret is standing in the cold at 2 AM in Flagstaff, smelling propane, and convincing ourselves it was fine.
