Well, used the challenger first time this weekend, (a working weekend) enjoyed but have to learn the various ins and outs of this unit. Have a leak or moisture condensation in the overhead tv cabinet in front...?? Doesn't make sense, but moisture dripped out of the cabinet that holds the oh TV between driver and passenger seat. I couldn't seen any problems but if weather permits today will get a ladder and look. LP gauge in unit doesn't register properly, can't get the lights to turn on from switch on the entryway, but will individually. Little things I believe, but do need repaired. Was neat not going to a motel, or having to drive the 98 miles back to the house. Didn't set the levelers and it rocked, lol. Have to fix the cruise, it would not shut off, with the switch or the use of the brake, Finally, had to pull over and shut it down, to get it to stop. Didn't use it anymore coming in. Will look at it today.
