Look very closely at the fit and finish of the Thor. We looked at two in our search for the 'perfect' rv. the first one, we didn't get past the fact that the slide would not go out, even after techs worked on it for an hour. The second, the slide worked but the fit and finish were awful: parts of the floor were coming up and other parts of the floor didn't even go all the way to the wall, trim pieces were missing or cut short for the space they were supposed to fill, doors were not attached straight. Overall, our walk throughs of the Thor Super C were very disappointing.
We found one Jayco super C on a lot. We fell in love with it immediately. We found no problems with it at all. But, it was three feet longer than we wanted. We were willing to buy it anyway but the dealer would not come down from list price. He offered all kind of "special enhancements," free oil changes and free yearly inspections and the like, but it wasn't a value add for us as we didn't intend on staying in the area.
In the end, we ended up with a class A. But, if the dealer had been willing to work with us on price, we would probably be driving a Seneca today. There is no way we would have purchased the Thor based on our limited experience with them.
