In regards to the OP (Original Post), as I saw already mentioned, if money is no object then its up to whatever you're looking for. But as it is with most people whereby money is an object, I would suggest looking for used. There are tons of RV/trailers out there for sale on the used market. And dealer "used" will be more expensive too. "New" is always nice and fun no matter what you're buying but honestly I cant figure out for the life of me what cost so much in the RV/trailer industry which justifies the insanely high prices these things go for. Or.....is it that people just pay it? Who can afford something almost expensive as your house but you only use two to three times a year? Plus if you're lucky enough to have room to park it at your house otherwise you have to pay more money to park it somewhere.
If you're a savvy/wise shopper then you can find some great opportunities buying used. Not all stuff is beat up or abused and stay away from anything lived in. When we were looking for a trailer, we mistakenly stopped in at the dealer and sat in some new models. Yes, they are very attractive and smell nice but the stratosphere sticker price makes them terribly ugly to me. So instead we looked around for about 2 years and found a trailer 6 years old in great condition that worked for us. And it was around 1/4 of its original sticker price. That said, we had the time to look around and were in no hurry as we had particular features in mind.
