I have a Transit AWD. Bought it in 2020 and built it out in '20 and '21. Use it to camp in while traveling to/from MTB and paddling trips. We have magnetic screen doors across the slider and rear doors such that we can have a nice breeze flowing through at camp without letting a single bug inside.
35k miles on it now. Lifetime fuel economy = a hair under 18mpg.
Can confirm I've never owned a more surefooted vehicle. Our access road/driveway in ID is steep, slightly off-camber, and gets 15+ feet of snow every winter, plus a little bit of freezing rain to make it extra sketchy.
I have a Honda Element AWD and even with a shitpile of added weight in it I frequently lose momentum, spin the tires, and have to back down and try again. Have had to park it at the base and walk home a few times -- truly the walk of shame.
My wife has a Tacoma 4x4 and even with a shitpile of weight in it she is forced to get down into 4LO and beg her way up the hill many times each winter, and often back down and start again.
In the Transit I've never, not once, done anything other than drive straight up and park. Doesn't spin the tires, doesn't crab walk, just goes. Worst situation we've had was 3' of snow overnight on top of a packed snow/ice base. Xmas day '20. We'd been gone for a few days and when we got home the plows hadn't yet been out. Wife was so gripped I stopped at the base and asked if she wanted to get out. She thought hard about it and then stayed. Van just went right up. One of the most impressive vehicular performances I've ever seen. Wouldn't have believed it had I not been in the van.
We have Blizzaks on all three vehicles. Would not be possible to get home 4+ months of the year without them.
Can't speak to towing because I don't.
I had two Promasters before this Transit. Wouldn't wish them on anyone. Loved the idea of FWD and inexpensive, but they never delivered on anything other than constant check engine lights and dealer visits. If I have to say something positive about the Promaster it has amazing turning radius.
I have a few friends with 4x4 Sprinters, and two with 2WD Sprinters. Don't envy them their maintenance/service costs. Don't believe I'd be getting home most of the winter with the way that system's 4WD works.
My wife has a Go-Fast camper on her Tacoma. It's nice, and handy, and utterly lame when I want to make coffee from bed, or cook dinner out of the rain, or not have to unpack/repack bikes/boats to have usable space.
I've had two truck/camper setups in this lifetime. Standing at the tailgate to cook -- or having to climb inside to fetch anything -- while feeding bugs or getting drizzled on just got old.
Vans are not for everyone. But they're certainly the ideal for the way I like to car camp.
