I had a 2007 Damon by Thor. I just traded it last year for a 2016 Fleetwood bounder. You did not mention what year Challenger you are looking at. I would make sure you check your rail system on those slides before you buy. There were one or two years that the larger slides were being installed with a two rail, rather than a three rail slide system. There were problems. If you have not checked into the newer Fleetwood bounders, I would highly recommend it. There were a couple of selling points for me over the Challenger. The bounder comes with a 100 gallon fresh water tank and a 10 gallon hot water heater. The Challenger only comes with a 6 gallon standard hot water heater. The difference is night and day. Your husband will appreciate the **** pit area of the newer bounder rather than that of the Challenger. One other thing to think about. In 2016 we have a newer overdrive gear in the transmission. This does help to alleviate a lot of noise issues associated with the previous years noise complaints, but only when driving on mostly flat terrain.
