We own a Jayco A-Frame, I've always like the "A-Frame" style. Long story short traded it in on a TT after owning it for 6 months.
Problem was the heat pump/AC unit made by Dometic. IMO its a bad design. The unit was located under the bed which led into the storage compartment. It never drained the condensation from the A/C properly and we got a lot of water in the storage compartment.
After 4 attempts to rectify the problem, including one total replacement of the unit the dealer gave us a total refund on it toward the purchase of a TT.
If anyone is looking at an A-Frame with these dometic heat pumps/AC units beware. If you research it on line you'll see I'm not the only one who has had issues with it.
I believe Jayco has dropped the A-Frame pop-up from its line.
