We've had our 2017 Challenger 36TL for a little over 1 year now. It's been, for the most part, a good experience. We've taken some long trips over all kinds of roads and the Challenger has held up pretty well. We did have 1 sliding door come off the track ( PA has some mighty rough roads). We do like the large living room and kitchen in the 36TL, but wish they had made it a 37TL to give more room in the bedroom and a pantry by the frig. Oh well, nothings perfect. Still haven't managed to get out of the heat so far this summer (sick child); but hope to get away by the 2nd week of July. Anyway, I am enjoying reading everyone's posts and getting some great information. Thank you!
