Go with the Jayco. We looked at one and really liked it, then looked at a Rockwood and liked that better, and got that, but I wish I never would have bought the Rockwood. The name says it all! That is a whole other story.
One thing to check for on the TT is where the front the leveling jacks are. Make sure they are either on the frome or as close to the frame as possible. I have found that some Ulta Lite TTs do not stabilize well when the fromt jacks are way out on the tongue.
