One major change starting in the 1998 models is that the slide out floor is lower than they are on the earlier year model TMs. The entry door is easier to set up. It is a matter of pushing pins into side clips for the bottom half of the door. Crank down stabilizers are standard equipment. The couch has a simpler system in order to change it into a bed.  The plumbing hot and cold pipes are the type plastic that cannot burst if it freezes. Thats all 1998 changes that I can think of for now.
