Hi there Artum Snowbird. Glad to see another B+ driver in the group. We bought a Lexington 255 last fall with almost the same floor plan as your Triple E. That back bedroom and closet wall were the deciding factors for us. We are under cover in sub-zero weather here in upstate NY looking forward to many happy miles starting next spring. Hope to see you on the road sometime. By the way, I fired up the furnace a couple of weeks ago when it was about 15 degrees and was able to get the air temp up to about 45 or 50 in about an hour. I'm not sure about camping in that weather, however. It would take a lot of propane to do the job I'm sure.
