Did a search on "older models" and got this link. It might have some of your answers:

You might also try a search on "floor plans". Be sure to set the date for something like 999 days or you will get very little to read. I also suggest you do some reading on wheel well modifications. Our '97 had the square ones and we did the mod with the helpful directions from some of the members. No need to avoid square wheel wells. Just add this to the list of things to consider changing if you get an older TM.
