I'd definitely lean towards a smaller rig for trips of a month or less. Smallish camper on a pickup is easiest. You can upgrade the truck to make it capable offroad and take off the camper to use the truck at home as well.
I have considered the Dodge PowerWagon in the past. A slide-in camper or bed topper is an option for light travel as well. On the flip side, these days I want a bit more comfort and a better bed. I have also considered the better offroad trailer options but, they don't offer a whole lot more and have a lot of added expense.
Coming from a motorcycle adventure past, I totally get the attraction some people have with Jeeps and similar pickup/SUV options.
This is what has me looking at the Grenadier and being backup to my daily driver is good as well.
