I actually prize my low range transfer case that comes along with the 4wheel drive more than the added traction. I find myself doing a lot of long steep climbs on loose sketchy terrain in the mountains and i like to put it in low range and utilize all the mechanical advantages of low gearing. I really do not want to bounce the van if i can avoid it.
The added traction is nice, too. I've utilized it more than I originally even thought i would. We do indeed come across mud boggs, mudddy hillclimbs, sandy beaches, snowy stretches, etc.
But I don't have another 4x4 overland vehicle, the van is it.
See for yourself why and when I use 4wheel drive. Maybe this will help your thought process.
Snow runs, of course.
In this picture below, i was actually last in line waiting as slightly bigger rigs were stuck in the snow. From a point that is out of the picture frame ( you can't see the actualy beginning of the snow on the road) I went over the berm on the right hand side of the road (left side of picture frame ) then thru the mud bog, up and over the berm again back onto the road, then reversed up to the front of the line while they continred to get Jeeps unstuck from the snow. Everybody stopped what they were doing and couldn't believe it when I cleared the entire mud run. i was a little worried as it slowed and then continued at a mud slingin crawl until I cleared it.
In Owhyee, the rain turned the roads into instant Gumbo mud. 4 wheel drive was absolutely imperative.
I would never have attempted this campsite without 4 wheel drive for the sand and uneven terrain.
In Eastern Washington I saw a Tacoma stuttering a bit at about the same point my van is in this picture...before my attempt. it was enough to make me a little nervous. The back end of the Taco was stuttering up and down, signs of losing traction...but he made it thru. The van made it quite smoothly actually.
I don't think I would have tried it without Railvan and his 16,000lb winch behind me.
I would not have taken the route we took to get to the Three Corners marker of Idaho, Wyoming, and Oregon without 4wheel drive. Hills and slick mud and a few water crossings. I would not have wanted to stress out the others in the group.
A locker may not be enough in this case with one tire off the ground and the other rear tire on a slick rock or in the mud. The pull from the front is a welcome addition.
I would not have driven the beach from Westport to Tokeland without 4wheel drive.
I suppose one could do this in a 2 wheel drive, but i would not have scouted out river camping on the way home from a California sea kayaking trip like this without 4wheel drive.
After all day of driving FS roads in Washington's Cascade Mountains, I would not have wanted to try these mud crossings and snow crossings in 2 wheel drive. ( I shot these of Railvan as he followed me thru them)

But that's just me and the places I want to be in my van.
It was never a question while I was building my van. I knew I needed to find an AWD, then swap the T case, install taller AT and/or MTs, and change the gearing and add a locker. Personally, I'm really glad I spent the time, effort, and money.
How much do your circumstances look like mine?
