Epilog: Traded in the 2012 Jeep for a 2013 E350 passenger van. It's rated for 5000 pounds & up when properly equipped, aftermarket parts allowed, and it has pretty good ground clearance. The downsides are 15 mpg highway without a trailer, a large turning radius, and it will be tough to pull snow off the roof.
Bonus features are flex-fuel so I can try that E85 currently saving $0.60 a gallon) and more room inside. I'm not going to go "Class B" with it, it's a low roof model that fits in 7 foot parking garages, but I might try to swap some seats for a bunk or what-ever. Best wishes to the guy who gets my Jeep.
