You mentioned insulation......DRV has three and a quarter inch thick walls with a better r factor. We have the Elite Suites and got the 15 K btu air conditioner/ heat pumps. The electric fireplace was reluctantly ordered and were surprised how much we enjoyed it. Some folks have great luck with their DRV products but we have had numerous problems. Lots of things broke like the TV and surge protector. It is just a******shoot as most have had great luck with DRV. They are getting everything fixed for us and we like the trailer as far as finish quality. We notice the better r factor as the heat and air conditioner are not cycling all the time and there are no drafts. The price on these trailers really vary a bunch. If you end up considering this unit, send me a message and I will reply and let you know what I found and who we found to be the most informed and helpful dealer. This is our fifth RV and have enjoyed every one.
