best model of Keystone 5th wheel?

I know I'm late on this thread but I thought some of you might find this interesting. I just took my 2016 Montana 3711FL to Tom Johnson's in Charlotte NC for warranty work (breaking slide out cable and loose A/C fan) anyway Tom Johnson just sold to camping world and are a VERY busy service center. The woman there was very very helpful and I asked her what manufacturer has the least amount of problems and what manufacturer has the best warranty response. Her answer to both was Newmar was number 1 and Keystone second. She said all the rest were very difficult to deal with on all warranty work.
