About the height, when up the inside is about 6' 2". I was in the AK camper factory and Bryan was building a extra tall top for someone who was taller than that. So I suppose possible. Used I would imagine har to find taller.
PS. I sold the 2016 Ford 350, the one in the icon pic. All was fine with the Ford for the AK camper, but we decided to go for a bit more room, for camera gear and dog and a smoother ride since we will be on 1000's of miles of dirt roads, including the road into our off grid cabin when we return. The 3500 crew cab Chevy, with the 7 foot flat bed is working great. A lot of locals up here have Chevys. Hmm. We LOVE the camper and our truck set up. It is meeting all our needs, expectations of all the planning of the rig and FUN and easy to set up.
We left Flagstaff June 15th and still travelling. We headed north on the Cassiar (awesome and not crowded), then Dempster to Tuk and now going south on the Robert Campbell. We are travelling slower than most, and on the roads less traveled, a lot of side wanders, and I can see how we could spend 5 months going north and south. Our 3 month plan may not be enough. Will keep posting when we can and till the end.
