This sounds like quite an intriguing challenge of yours.
More details as to your specific budget, needs/wants, lifestyle preferences, comfort expectations and intended use really would be necessary to give you any useful advice.

We once lived up in Yukon/Alaska/Northern B.C. @ for two months in an 8’ long, 60” high 1/4 cab over shell with essentially nothing built in in it, on a half ton reg cab, long bed 4x4 with a six cylinder engine and had a great experience doing so.
Would that combo work for everyone? Certainly not….so, again, fill in the blanks for us about your plans and maybe we can help you out.
I don't think he was asking for advice. He is looking for a rig for sale.
