We're looking at the 3210 and local dealer doesn't have any on the lot. Dh drove 4 hours to see one (without me) last weekend, but found the salesman completely unknowledgeable and the brochures outdated, and he didn't have enough time to look at everything. One question he couldn't answer for sure was whether there are heating and air conditioning vents in the garage. He thought there were, and I'm thinking that with the electric beds in the garage there ought to be. Can anyone say for sure?
