Probably then, when it comes time to buy, I'll most likely pick up whatever seems to be the best deal. And since most are 4WD around here, that's probably what I'll end up with. Doesn't sounds like anyone had any major justification for 4WD other than the traction issues.
I'm in rural AZ, and despite being about as far south as you can go, 4WDs are most popular. No snow issues, but locals could spend a good bit of time on dirt roads, crossing flooded washes, etc. And then there is that cowboy mentality thing.
I have never really needed 4WD in my 1/2 ton trucks and have spent plenty of time off road both here and in OR and WA. But then I also didn't venture into the outback that much when it was wet and sloppy.
Now I'll be towing 10,000# around the country on paved roads and probably never venture into the dirt with this rig. But some did mention the possibility of wet grass, soggy campgrounds, and backing up hill, and I could see those as issues. I could use my portable winch for those situations, but it would be a lot simpler to just hit the 4WD button.
Thanks to all for your input.
