We bought our first motorhome washer dryer combo in March 2025 after spending $47 at a laundromat in Tucson and realizing we were done hauling trash bags full of dirty clothes across parking lots. Tony said we should research more. Gina said we were buying one that week. We compromised by buying seven different motorhome washer dryer combo units over the next four months, testing each one for at least six weeks of full-time use while traveling between Arizona, Oregon, and back to Florida. Four of them died. One leaked water into our bedroom. Another one tripped our breaker so many times we started calling it the Circuit Killer. By September, we had three survivors, two clear favorites, and about $4,200 worth of lessons learned the expensive way. Having the right setup has completely changed our full-time RV lifestyle, and we wish we had figured this out sooner.
This is not a review based on spec sheets or what manufacturers claim. This is what actually happened when we washed clothes every single day for six months in a motorhome with our motorhome washer dryer combo.
The Three Motorhome Washer Dryer Combo Units That Didn’t Die on Us
The Splendide WD2100XC vented combo is the motorhome washer dryer combo we kept installed. It sounds like a small jet engine during the spin cycle, but it has washed and dried our clothes, Maggie’s blankets, and every towel we own without complaint since May. We ran it in 110-degree heat in Death Valley and during a cold snap in the Cascades where temps dropped to 28 degrees overnight. It kept working.
The LG WM3555HWA ventless combo came in second. It wrinkled our shirts if we forgot about them for twenty minutes after the cycle finished, but the TrueBalance system meant we could run it at 2 AM without waking up. For a family traveling with kids or anyone who needs to do laundry at odd hours, that silence matters more than we expected.
The Giantex portable twin tub survived, but we gave it to Tony’s brother after two months because washing and spinning in separate tubs felt like doing laundry in 1987. It worked fine. We hated using it.
The reason these three outlasted the others comes down to one thing: they were designed to handle vibration. Motorhomes shake. Roads are rough. Cheap bearings and flimsy drum mounts do not survive six weeks of highway travel, no matter what the Amazon reviews say.
Why Four Expensive Units Failed Within Months (And What We Learned)
The first failure happened in a Walmart parking lot outside Flagstaff. We were three weeks into testing a ventless motorhome washer dryer combo unit we paid $890 for, and Gina opened the door mid-cycle to add a forgotten sock. Water poured onto the floor. Not a little water. Enough water that we were on our hands and knees with every towel we owned, soaking it up before it reached the carpet. The door seal had cracked. We later learned that ventless units build up condensation inside, and if the seal is not perfect, that moisture finds a way out. We returned it the next day.
Two more units died from electrical issues. One pulled so much power during the heating cycle that it tripped our 30-amp breaker every single time we tried to dry a load of jeans. We could wash clothes fine. Drying anything heavier than t-shirts meant resetting the breaker, waiting ten minutes, and trying again. After a week of that nonsense in a campground outside Bend, Oregon, we pulled it out and sold it on Facebook Marketplace for half what we paid.
The other electrical failure was worse. The control board fried itself during a power surge at a sketchy RV park in New Mexico. We smelled burning plastic, unplugged it immediately, and spent the next two days trying to find a repair shop that would even look at it. They quoted us $340 for a replacement board. We bought the unit for $650. We threw it away.
The fourth failure was a seal issue on a different vented model. It worked great for five weeks, then started leaking from the back during the rinse cycle. Not a lot, but enough to leave a puddle we did not notice until the subfloor started feeling soft under our feet. That one taught us to check underneath the unit every few days, which is something motorhome manufacturers never mention because they assume you are installing these things in a house with a concrete floor and a floor drain.
What we learned is that RV appliance manufacturers do not actually test these motorhome washer dryer combo units in moving vehicles. They test them on a bench in a warehouse, and if the drum spins and the water drains, they ship it. Full-time living means your washer is bolting down the freeway at 65 mph, rattling over potholes, and sitting in the sun while the interior hits 95 degrees. Most units are not built for that.
The Installation Disaster That Cost Us a Week and $800
We installed the first unit ourselves in a campground in Sedona, and we did it completely wrong. Tony ran the vent hose out through a sidewall without sealing the opening properly. We used the existing hole where the previous owner had vented a furnace, figured it was already cut and ready to go, and shoved the four-inch dryer vent through it. We caulked the outside. We thought we were done.
Three weeks later, we were parked on the Oregon coast during a rainstorm, and Gina noticed a dark spot spreading across the bedroom ceiling. Water was running down the inside of the wall where we had installed the vent. We pulled the vent hose out, looked inside the wall cavity, and saw black mold growing on the plywood. The rain had been getting in around the vent opening because we never sealed the interior side or properly flashed the exterior. We spent $800 hiring someone in Portland to cut out the damaged section, replace it, and install the vent the right way.
The second installation took three hours and involved a lot more silicone than we thought was necessary. The installer took the vent assembly apart, sealed the raw edge of the cut hole on both sides with silicone, let it cure for four hours, then reassembled the vent and caulked every seam on the outside. He also added a rain cap we did not know existed. That vent has not leaked once in four months, including two weeks of heavy rain in Washington.
What we wish we had known: the hole you cut through your motorhome wall is an open wound. If you do not seal the exposed layers of fiberglass, plywood, and foam, water will wick into those materials and cause delamination. Delamination repair starts around $2,000. Doing the vent install right the first time costs $200 if you pay someone, or about $40 in materials and half a day if you do it yourself. We learned this lesson the $800 way.
The one piece of advice that would have saved us: take the vent assembly completely apart before you install it, and seal every surface that will be inside the wall. Do not assume the factory flange is waterproof. It is not.
What Six Months of Daily Use Actually Costs You (Water, Power, and Repairs)
We spent more on electricity than we expected. The Splendide WD2100XC pulls about 1,500 watts during the drying cycle, which does not sound like much until you realize that is 12.5 amps on a 30-amp connection. Run the air conditioner at the same time and you are flipping breakers. We started doing laundry in the morning before it got hot, which meant we could skip the AC and avoid the power juggle. Over six months, we estimate the washer dryer added about $18 per month to our electric bill when we were plugged into shore power. That is based on running one load per day, six days a week.
Water usage surprised us in the opposite direction. The Splendide uses about 13 gallons per wash cycle, which is less than we expected. We were worried about running out of fresh water when boondocking, but one load per day only used 91 gallons per week. Our fresh tank holds 100 gallons, so laundry was not the limiting factor. Showers were. We could do laundry for six days before needing a fill-up, but we needed to refill every three days because of showers and dishes.
Repair costs were minimal on the units that survived. We replaced the lint screen on the Splendide once after Maggie’s blanket shed enough fur to clog it completely. That cost $12. The LG needed a firmware update after it started displaying an error code we could not clear, but that was free through their app. The biggest unexpected cost was dryer balls. We went through three sets of wool dryer balls because we kept losing them in the folds of our comforter. At $8 per set, that added up to $24 over six months, which is ridiculous but true.
Total six-month cost for the Splendide: roughly $108 in electricity, $12 for the lint screen, $24 for dryer balls, and zero dollars for water because we were paying a flat campground rate most of the time. That is $144 total. A laundromat would have cost us about $35 per week for the same amount of laundry, which works out to $910 over six months. The motorhome washer dryer combo paid for itself in saved laundromat trips, even after the $800 installation disaster.
Before You Buy a Motorhome Washer Dryer Combo: The One Question You Need to Answer First
The question is not whether you need a motorhome washer dryer combo. The question is whether you have 30-amp or 50-amp electrical service in your rig. We met a couple in a campground outside Boise who bought a beautiful stackable RV washer dryer setup, installed it in their Class C, and could not run it because their motorhome only had a 30-amp connection and the dryer pulled 22 amps by itself. They could not run anything else while drying clothes. No fridge, no AC, no TV. the dryer. They ended up selling the set for half price and going back to laundromats.
Check your electrical panel before you spend a dime on any motorhome washer dryer combo. Find the main breaker and look at the number printed on it. If it says 30, you need a combo unit that pulls less than 15 amps during the dry cycle, or you need to be very careful about what else is running. If it says 50, you have more flexibility, but you still need to check the specs on any unit you are considering. The National Fire Protection Association has guidelines on electrical loads in RVs, and they are worth reading before you start plugging in appliances that pull serious power.
Measure your space. We assumed our closet was big enough for a standard 24-inch combo unit. It was 23.5 inches wide. We had to remove the closet door trim to make it fit, and even then it was tight. Do not trust the floor plan drawings. Measure the actual space with a tape measure, corner to corner, and then subtract an inch for clearance and ventilation. If the unit you want does not fit, it does not fit. Forcing it in will block airflow and cause overheating.
The next step is simple: go look at your electrical panel right now, write down the amp rating, and then compare it to the specs of any motorhome washer dryer combo you are considering. Do not assume it will work. Check the numbers. We have been using a digital multimeter to verify amp draw on every appliance we install, and it has saved us from making expensive mistakes. We learned this by watching other people make expensive mistakes, and we are telling you so you do not have to spend months testing different motorhome washer dryer combo options like we did.
