I have had 4X4 on my last two trucks, 1st truck could get stuck in a flat grass field.
We also 4 season camp, winter is mostly mild on the Oregon coast, well came home one trip with highway 26 snow covered over the coast range about 30 miles. Didn't have any issues including getting going after having to stop for a spun out car on an up hill grade.

If 4x4 has saved you one time you will know its worth. In my case it is many times -towing and solo - so you know where I stand. Family on board, 5th behind and truck starts sliding sideways heading up a grade on rain wet fresh ground concreate in summer - 4x on and truck pulls strait out - priceless. Many winter pass scenarios where the truck goes from tail happy in 2x to on rails in 4x. I think the real question is with the way the weather is now why would you not have it? With the amazing traction, especially with the weight of the diesel up front it really is a great tool.
Camped at two state parks this summer. Both sites I backed up a gravel incline and was slipping. I put it in 4x4 and in we went.
I'm not in a area where we get snow all the time but we do get snow and I work at a hospital so not going to work isn't an option. I got the 4x4 for safe work driving when it is bad and was sure glad to have it getting into those camping spots.
I agree with others. I only buy 4x4. Partially it is because I live in Canada, and well, we need 4x4 during heavy storms.
But a more obvious example just happened this past weekend. I was going to my friend's camp and in one section of the dirt road, it is a severe hill, with a cliff just off to one side. FYI, I was towing my TT at the time. Well before the hill I was prepared to throw it into 4x4 if needed, so it wasn't a close call at all. BUT, as soon as we got into the steep part of the hill, the truck's back tires started spinning. Threw it in 4x4, and off we went. Now, if I didn't have 4x4, it could have been quite a disaster. Possibly life saving for my family.
I've only gotten into one situation where I needed to put the truck in 4WD when I was at quite an angle and on grass on a slight incline. My rear wheels were spinning and starting to dig in, and I had to put it in 4WD. If you anticipate never having to be in that position, or not having someone around to pull you out, then 2WD would be fine. If I ever upgrade to a dually just for pulling a FW, I would consider a 2WD.
