I dunno, most of my moto buddies are getting close to retirement age....some went the ADV bike route for a bit, tried to get their better halfs to come along...most of them don't care for long hours in the saddle, many of them sold the ADV bikes and bought UTV's. Much more enjoyable experience for everyone.
It is strange, when we were kids didn't matter what you rode, bike, quad, trikes, go-carts, etc....no one cared, we just had fun. Now there is Us against Them mentality...with well....just about anything and everything.
Have met good and bad people in all forms of recreation. I mostly ride dirt bikes, have been almost take out by Jeeps, UTV's, Quads on transfer sections...and had head on collisions on single track where other dirt bikers think it is a race track. Also have met some very nice polite people too, where we both yield to each other, stop and chat it up a bit.
Years ago there was an article written by an environmentalist in one of the local rags, putting down off-pavement motorized recreation...I wrote in basically saying we all aren't bad, they actually published my letter. The author and I e-mailed back and forth, asked her if she ever been on a quad or UTV...she said no. Said to her, how do you know if you don't like something if you never tried it, even invited her out to help with one of our trash cleanups, and I would teach her how to operate one...she refused.
So to the OP...yeah I would overland an UTV, just do what we do with the bikes...use the trucks as basecamps...and go further in with the UTV. I'll often drive the truck to eat up the pavement miles, and still do some camping off the bike away from the base camp.
