Wow, great information added here after I assumed the discussion was done and stopped checking, lol. But not too late, since I still haven't bought an RV. I looked at a few travel trailers at dealerships, but I hated the interior layout and construction quality with so much passion I sort of stopped bothering to go look at others since they all seemed to be pretty much exactly alike, at least in my severely limited price-range.
But now I was gifted some money by a family member (not a huge amount, but enough to make a real difference) and am changing the types of RVs I'm looking at. I just emailed every good-looking Craigslist listing within 2-3 hours of me and got a response to the "wanted" ad I posted there too, so hopefully I'm making progress on this again.
I haven't ruled out a dealership, but didn't see much I was terribly interested in in my new price range when I was looking at their websites.
