Moving up from PUP to TT, what to expect

I was looking at TT's myself simply for the ease of set up. The Pup is paid for, and has more room (or so it seems)than some TT's. Mine does have a slide out, Toilet, and A/C. What I would expect to be different on the down side....Towing -can't see all the way around....windy days.....at the campground -backing in (again, can't see all the way around)....at home -storage may be a problem for some (not us though, plenty of room).....use as a guest house for those relatives you'd much rather not spend the week with.....the good -ease of set up, especially in crappy weather....can pull off the road and take a rest, or something to eat at any time
