My insurance co. considers 4500 and 4500 series commercial. that makes it cost prohibitive. 4500 Ram has only about 500# payload increase, and a higher curb wt. If I get a Bigfoot 10.4 I may carry extra water since their gray and black tanks are large. as far as STUFF. I really like Stuff. Mosquito tent, inflatable boat, extra gas for Honda generator. pretty much anything I don't want in cab of truck or in camper. Heck, I may even get another English Bull Terrier. He would get the back seat.
My next trip to Alaska will probably be in excess of 4 months. This next camper will be my second home. Maybe start spending time in Az.in the winter. I hear they play Pickleball out there. :)
Arctic Fox 1150 can be used with the slide wall cranked in with no problem. Still I would prefer the Bigfoot for floor plan and clam shell design.
