I spent years in the trucking industry and even owned a couple of tractors. The design of the system (tractor + trailer) was such that a 13k lb tractor could pull a 15k trailer with 45k of cargo and never feel out of sorts.
Towing an RV is quite different and requires more effort at keeping the system balanced. The heavy tongue weight is a concern as the weight distributing hitch is forcing a great deal of pressure on the hitch to push the vehicle's front end down, thus balancing the load.
The 80% of capacity rule is one I've heard before. I seem to think it was invented by someone who convinced his wife he needed a 1-ton dually (for him) to pull their 7,000 lb trailer. In the trucking industry, we called these guys "big strappers".
The OEM rating for gross vehicle rates are their conservative engineering calculations for maximum capacity as the average Joe only has average skill when it comes to handling heavy loads. The corporate lawyers would have it no other way.

This is the primary reason my TV is 4WD...
Winter...
PUs don't have the best traction in the rear end.

How About Chains?
My Tundra is 2wd. I bought it with 2wd because it was about 3k cheaper than 4wd, the mileage was better by 1 mpg, the payload was better by 100 lb and no 4wd maintenance. I figured that I would not need 4wd because I would not get stuck because it had limited slip. Wrong- the limited slip is electronic and it really sucks. I have had it out in the snow once and it acted just like a truck without limited slip- one of the tires would spin. Anyhow it needs a locker, but as far as I know, nobody makes one. I have not gotten stuck boondocking, but it is just a matter of time. Has anybody used chains to get unstuck pulling your Airstream out of some slick boondocking locations? Seems like it ought to work fine, and the cost is minimal. It sure beats calling a tow truck.

I have not ever been stuck with my airstream because I have very capable 4wds to use.I have how ever used chains quite succesfully on 2wds.They will make a huge difference in most snow conditions and in the slick clay,but not so much in the bottomless mud situations

I agree that most of the time you don't need 4x4, but when you need it, you need it. I would have been stuck in an isolated campsite in Alaska without 4x4, believe me, it would have been a long walk to get help. And, just now, leaving Massachusetts with a foot of snow on the ground, needed the 4x4 to get the AS out of its parking spot.

Agree with wrochdvm. Most the of the time you do not need 4wd; however, there are times when it is helpful.

The cost of having 4x4 vs 4x2 is virtually nothing especially if you trade vehicles every 2-5 years.You pay more to have it upfront but then you get more for it vs 4x2 when you trade or sell it.They are actually more desirable in the used market place.
Maintenance is minimal just remember to lock it in every month or so to keep everything lubed.
But when you need it you really need it ....period
Cheap peace of mind.
