We absolutly loved the Host tripple slide when we looked at one,,it's the only tripple I've seen in person,,but I was amazed how much interior room there was, plus the basement full slide shelf, and that couch was what I really liked. Nice spot to sit and relax for sure. But, Im not wanting to deal with the combined wt. of a Trip slide and towing 6000lb boat, I have the rig to do it, but not the want. Thanx for the info on the slide manu. and Aluminum framing. As a welder and Fabricator, I can apprecate the the net yeild of strenght to wt of Aluminum. We don't "plan" on camping in winter conditions, maybe a late season hunting trip time to time in the mid west. Any issues that slides have on sealing cold air or dust for that matter. I know its probably some, but just wondering if its something I should know about,,,gregg
