then I think you need to really consider what you truly need/want for the future. if you are truly going to get a motorhome of some sort then that will dictate what type of trailer you want now. IMO, you have 2 choices (so to speak).... 1) just a big enough trailer to fit the rig and a little space left over for some work area 2) skip the motorhome and do a trailer that has living quarters (Like what I have or like Mikes). Mikes enclosed has living quarters in the front section and plenty of garage space too. pretty sure his is a 40' though
I'd hate to see ya get too much trailer and then try to put it behind a large motorhome. that will limit where you can go.
just food for thought.
