You said you want a garage and an open floor plan..usually the 2 are different. There are several bumper pulls in that size range, most of your list is just mass-produced trailers and will probably have some type of problem with them in the beginning if you buy new. I know our Keystone has very poor insulation in it when trying to cool it down when it is hot outside. None are really built for full - timing. Depends on how fancy you want to get with the interior.I would probably add KZ to your list of trailers to look at.
