I can't offer any better advice than what's already been offered, but I can give my limited experience. The bride and I picked up our TT on the 19th and drug it 1100 miles home. We started looking at a pup but quickly changed our minds when we looked at a couple of hard-sides. We picked the 23B as it was a great weight for our existing TV (03 ford expedition 5.4). We were lucky in that we already own a suitable TV. We picked a hybrid model because of the combination of the shorter length vs. The avail room when the beds are extended. We plan to travel this great country of ours in extended outings of 30-ish days or so once I reitre. The bad news is that's still 5 years out. We have a single g'son and expect he will spend time with us, oh yeah his parents too. We will spend the next few years sorting out if this size and configuration that is right for us. I can tell already that the hybrid is a bit more of a pain to set up and strike but manageable - so far.
The hardest part of our first outing was scrubbing the love-bugs off the front end after we got home.
