Hi Mark, seems to me you are overthinking this by a whole lot - 6-8 weeks isn't a problem if the vehicle is well-maintained
park it with a trusted soul who moves/drives it once a month or so, and looks it over before you fly in to pick it up - throw your stuff in and go - list of cruiser contacts along the planned route, AAA Premium plan, spare battery, CB and HAM, paper maps
personally, I have a policy of no-camping where there is infrastructure or 'civilization', and even if money was short, I'd rather stay in the rock bottom motel of a rinky-dink village in god-forlorne BFE
so two 80 series did just fine for my sister and me on 10 days of a 2500-plus miles south-north-south US trip in 2019 - no fridges, but two Pumas - we did some remote trails, no serious rock-crawling, some dirt roads, some 80% asphalt
