This is a follow up review to my first review with problems that continue to persist on my 2017 Thor WS31 motor home.After the 2nd camping trip (8/20thru 8/27)I now find out that the black water tank & the grey water tank must be installed incorrectly. After dumping the black water tank every day and a half I ran water from sink in bathroom and kitchen sink with both valves closed on the tanks and the black water tank filled up and the grey water tank continued to show empty.I now have a water leak from shower area that runs water onto the floor in front of the Fridge. Do not know if this issue is due from having to take motor home back to dealership after the first camping trip due to water valve not turned on to icemaker. Fridge had to be pulled and the water valve turned on. Do not know how these problems are not checked at the Thor factory. Seems to be no quality control check-off at Thor factory(additional examples are cabinet doors falling off when opened and screws and wiring that was left under slide-out). I will now have to take motor home back to the service dealership from which I purchased the motor home and get repaired, And the service department will do a outstanding job repairing as always. Service department will continue to have job security while Thor is ignoring quality. I JUST want to go on a camping trip without returning from trip and taking back to dealership for repairs. I would love to communicate with someone with authority at Thor and see how these failures were not caught at the Thor factory. Unbelievable!!!!!!!!!!!!

Bought this unit from a dealership in Saskatchewan. When we first purchased this unit it went through the first camp without issue. 2nd trip the awning retracted half way and blew the #7 fuse. The slide wouldn't retract either. The fuse panel turned out to be wired incorrectly and the awning wiring should have been in the # 8 fuse position. Discovered a pile of garbage, screws, wiring, sunflower seeds and sawdust behind the fuse panel and water pump. Where is quality control on clean up at the factory? Developed a water leak after the ice maker was turned on.The rear area of the slide has cut the vinyl flooring as it was glued down improperly and puckered. The 40" TV bracket had the support screws falling out as they were screwed into 1/4" plywood that offered absolutely no support and when the unit is driven the vibration wiggled 3 out of 4 screws loose, also found the upper valance and wall area at the front slide smashed and part of the actual plywood wall hanging loose by the wall paper.....come on Thor!! Some of the finish on the cabinet doors where scratched and streaked. Some of the cabinet cross members were cracked as they obviously never predrilled screw holes in the hardwood. What is going on with factory quality control? We are trying to fix these issues under warranty, but I can only find one place in all of Manitoba that will consider fixing any issues. The dealer is over 8 hours away if I have to take it back to Saskatchewan. They (the dealership) have been great with contacting Thor and authorizing the work but to have all these quality issues come after purchasing this unit is ridiculous $140,000 bucks for me and my wife to clean up their messes. The screws, dust, dirt and garbage shows how they care about their product. I've bought my first and last Thor Motor Coach, ever!!!! It's to bad because I love the looks and feel of driving a "C" Class, but after this one, it will never be a Thor again!

I picked up motorhome on 7/18/17. This was after the first WS31 that my wife & I picked out could not be used due to rails on slideout installed incorrectly at the Thor factory. This motorhome was brought to Alabama from Louisiana. The one delivered on 7/18 that came from Florida had to have motor changed out on the electric awning. The service department did a outstanding job of repairing this problem. Had to bring motorhome back on 7/19 due to issues with the TV's. Wiring had shorted out and new antenna was put on which corrected problem. Service department had motorhome ready that evening. Tried motorhome out at a campground the next day(7/20) and the ice maker would not work. Taking motorhome back to the place of purchase on 8/4 and leaving with service department to correct this and other small issues. One issue was a cabinet door above the dinette fell off. I thought Thor was a quality camper but something has changed with the poor quality at the factory. Another issue was screws was left under the dinette area of slide out. This should have been corrected & cleaned at the factory. If someone with authority from Thor reads this review....GET YOUR POOR & UNACCEPTABLE QUALITY PROBLEMS CORRECTED!!! Not one customer should buy a new motorhome and go through these kind of quality problems originating from the Thor factory. The service department have corrected problems in a timely fashion and I would recommend the sales staff & service staff to anyone. Would I purchase another Thor camper? I do not think so.

My experience with this motor home has been disappointing. It has spent months in the shop for poor workmanship issues. I have to bring in back 4 times missing many of our planned trips. Despite this, new problems emerge with every trip. This last trip that radio stopped working meaning my cameras were unavailable - a safety concern. I constantly have outlets that blow out. This is very disappointing. Moreover, Thor's response to get the repairs and correct materials approved only adds to my delays. Part of the delays in getting things done right belong with the dealer, Mike Thompson, who cannot seem to order the right parts in a timely manner, but the quality of the Quantum is where the blame lies. The cabinets are junk and fall apart, the finishings are also poorly installed. I have the entire rear window trim collapse. Trim comes apart as well not being properly installed. The user manual is worthless. Try to figure out what fuse is what, your cannot with the Thor manual. To be honest, most of the problems are minor, but in their collective they show a disregard for quality.
