And Leveling in a Motor Home is a lot quicker and easier than with a TT, at least for us it sure is. We also don't have jacks, we just use Lynx Levelers and haven't had a problem. And we camp at state parks up here in New England a fair amount, so it isn't like we're always on paved flat spots at RV parks. We do carry two sets of Lynx and often use all of them.
I would not limit yourself to only Thor just because that's what the local place has. Spend some time looking around and don't be rushed into a decision.
Happy Shopping!
