It will be interesting to see what they do regarding frame sources in light of this development. Our Designers utilized Leland Engineering frames and Dexter suspension, and we never had any problems with either.
Rusty, I rolled under mine before I bought it to check it out. I put 'I know it's junk' in my signature because I was being ridiulous. We looked at an 07 Mobile Suite, but the gross on it was 15k. EW 12500. My truck is rated to pull a 12500 trailer. I don't want to overload it. That where troubles begin. The Lexion more or less took the place of the Designer, which is what we were really looking for. So far it has been a good rig. The Lipperd motor on the rear jacks went bad, was not sealed and got water in it. It pulls much smother than the 02 Jayco. It is by no means a low end, but a middle to upper end.
Had I had your truck I would have gone with the MB it is really a nice unit.
