desertone61 - You have gotten good advice - now it is a matter of personal preference. They were building the TL 252DS on a Ford E450 chassis when we visited the factory in 2005. Looked nice.
karebear and jeanniewes - Welcome to the world of Trail-Lite Class B+ owners. Hope you enjoy your new (to you) units as much as we have.
We have just returned from a 1300 mile trip and a 2100 mile trip. Not a problem even when encountering 103+ degree temperature. That is one thing that impresses me - the cab air conditioning cools the cab and the rest of the unit without too much problem. Price of gas ranged from $2.76 to $3.19 and gas consumption varied between 12.1 and 15.4 (tail winds help).
