We bought a '73 31-footer for a little more than a tenth of what you are considering spending. We have two boys. We were originally looking for something in the 27-foot range, and we were a little intimidated by the length of the sovereign
Now that we've taken it out and done some serious traveling and camping in it, we *love* the space. (And the reason we bought it was because it was the first one we all crowded into to take a look and didn't get immediate claustrophobia!)
Ours was in great, ready-to-camp condition. Yes, we will be making some little changes to customize it. Yes, things will break and need to be fixed or replaced. But you don't have to hand it over to a restorer; you can take it in to a dealer and have things done as needed. That's what our P.O. did, and he had the folder of receipts to prove it. :^)
Buying used, if we ended up not liking it or wishing we'd bought something else, we could easily sell this one for what we paid. We won't! We love her, and we're keeping her.
