2018 Thor Motor Coach Quantum 31WS Class C reviews

Like all RV owners we struggled for years emptying our black tank. We purchased all the tools to simplify the process. This is not an area easy to diagnose a problem but we finally did find the issue. The issue was an engineering flaw at the manufacturing level. when the black tank release handle was pulled, it did not completely open the valve and debris would get clogged and unable to empty. When we approached Thor it fell on deaf ears. They should have authorized a repair. They created the problem and should have fixed it. This is not warranty work. This is a design issue. To those of you who are considering an RV, avoid Thor. Show less

We have had trouble with the electrical system on this unit since we bought it. It has been in the shop more than it has been out camping. Every time we take it out, it has some other issue pop up. We are the second owner. The first owner only kept it long enough to drive it from Texas to Tennessee. That should have been our first warning not to buy it. But the coach is the perfect size for two people and the appearance of it, both inside and out, is spectacular! We should have had the remainder of the factory warranty as the coach was less than a year old but a Thor service rep told us the warranty was only for the original purchaser. After the one year warranty had expired, I called Thor again to check on recalls for electrical issues. She told me that we were entitled to the remainder of the factory warranty but since it had expired there was nothing they could do to help us. We have replaced house batteries twice and need to replace them again before we can take it out this year. We have replaced the regulator, the inverter, the Main on/off switch, fuses—-basically anything that had anything to do with the electrical system. And it is still draining the batteries, won’t charge them when we run the motor and/or generator. I would not recommend a Thor motor home to anyone! Show less
