Overall, we are very pleased with the unit so far. It has a great floor plan and we enjoy all of the appliances and kitchen layout. The bathroom and shower are thoughtful and very usable. We have had the usual "shake down" issues associated with newer units but are approaching 60 nights in it and 8,000 miles on it without any unexpected major setbacks. We have owned RVs for 30+ years and have had all types at one point or another. This is our third Class-A and the most expensive by far. Simply can't say enough good about the newer Freightliner chassis! The technology advances year on year are fantastic and make the unit far safer and drivable. Primary Complaints: Poor overall quality of construction of the coach and its assembly. The unit is thrown together far to fast and has little attention to detail. If Thor would enhance their build/assembly quality, they would kill the industry in this class and price range. Fuel milage is around 7mpg avg towing at 70-75mph. Yes, she has a drinking problem! We travel on business/pleasure 25-30k miles per year so we are more than simple passive owner-operator-campers with strong mechanical backgrounds and base our opinions on many different owned units, miles driven, and word of mouth conversations out on the road.

The lemon hasn't had working hot water. No hot water being produced by the AquaHot system for nearly 1 year. The Firefly readout says that it's working and status is "OK". There are no system faults. It was in the repair shop at Lazy Days of Wilmington, Ohio for 3 months. They couldn't fix it. I drove it back to the Thor factory repair, where the lemon was made, in Wakarusa, Indiana and they had it for two weeks. This is all warranty work. They stated on the work order that the hot water system was "On" for 2 days so no repair was needed. The only problem, still no hot water is being made. They were too incompetent to actually turn the water on to see if it was getting hot.

The steps wouldn't go out. I couldn't find the cause. Had a tech out and it ended up being a fuse holder that wasn't crimped enough. Thor paid the bill. We have had none of the issues that the earlier models had.

Bought a Thor Aria 3901. We like the looks, and the lay out, but really don't understand THOR not having a final check list in the factory before sending these motor homes out. Had nothing but problems with this motor home from day one. Not one to give out bad reviews but needed to let the public know about THOR motorhomes before they get sucker in buying one. Let you tell me if I am wrong or not. List of things that went wrong with this motorhome. 1 Door seal leak ( not installed correctly from Thor factory) 2 Huge gap in bathroom door (not installed correctly, from Thor factory) 3 Wash machine broke from the start! (from Thor factory) 4 No sealant on rear lights, latter back of roof (from Thor factory) 5 Passenger side slide broke (new motor) 6 Hot water heater broke (Replace water heater) 7 Furnace broke 8 Dash radio monitor broke 9 Drivers side slide out broke (factory cut opening crooked) had to rebuild entire side) So tell me they have a check list? I've heard all about THOR 's poor quality before I bought one . But I bought anyhow. Big mistake!! People should know what they are getting with Thor!

HAPPY WITH WOODWORK, SEATS AND FURNITURE, QUALITY COMPONENTS, HEAT PUMPS ON BOTH A/C's, ADDED CUSTOM MOUNT GARMIN 1090. RADIO AND BACK UP SCREENS ARE TO LOW THE 1090 FIXED THAT, WISH WARRANTY WAS 2 YEARS SO YOU DID NOT HAVE TO BE UINDER PRESSURE TO GET EVRERY LITTLE ISSUE FIXED ASAP, BUT I DID AND ALL IS WELL, OUTSIDE THE PAINT AND DESIGN LOOKS LIKE A HIGH END COACH PROUD TO DRIVE. OF COURSE THERE IS ALWAYS A FEW THINGS TO FIX BUT ALL DONE WITHIN THE YEAR YES I WOULD PURCHASE IT AGAIN

2021 Thor Aria has never ending issues since day one. 19 months and Freightliner TPMS system still not fixed. Refrigerator broke on 2nd trip. No heat on first trip due to circuit board had poor connect and had one wire harness not even connected. What was funny the Quility Control that employee signed off of right next to wiring. Camping World Indy I don’t think every did PDI on unit. Main slide broke on 4th trip and had to have motor etc replaced. Cabinet bottom fell out on 4th trip. Toilet in main bathroom won’t flush properly and you have to flush so many times you almost empty out your fresh water tank. Had coolant light on from day one and after two trips finally found leak. Coolant reservoir ran dry on 2nd trip. I can go on and on. Beware the quality has been poor and Thor is interested in quantity over quality.

Since day one tpms system inoperative spent 45 days At Freightliner to fix. Froze our ass off first and 2nd trip heater was never plugged in and circuit board not seated fully. What was funny the certificate sticker next to unit signed off that everything was ok. I guess what is said is there is no emergency/Care for Thor to want to assist with your on vacation and shit just keeps going bad.
