I recently purchased a 38FLFS and was finally able to get it home yesterday. I have owned several other Jayco trailers/5th wheels and pop ups. My previous 5th was a 2007 Designer. I must say, I am really impressed with this new Pinnacle. It came with a lot of options, including the Atwood, 4 point leveling system. Its a little complicated at first, but once I got it figured out, it is pretty slick. I had to laugh though, because the tech's at the dealer didn't even know how to use it when hooking up my truck.
Although it is a couple feet longer than my Designer was, 40' vs 37', it pulled about the same on the way home. I was a little disappointed by the brand of tires used, they are not Goodyear, not sure how long they will last on a trailer of this size.
