I'm not arguing one over the other. It is not as simple a question to answer as most would make it. IMO, a 4wd has the most benefit for towing, not from a traction standpoint, but the ability to move into the low set when trying to muscle 9000#s around in a tight uphill spot. The greatly reduced strain on the engine and trans as well as the ability to better control applied torque can't be had in any STOCK 2wd.
I can't (and probably wouldn't if I could) argue with anything you have said. I have been around 4WD since my dad bought the first 4WD Jeep station available for sale in the pacific northwest in 1949. I was 6 years old. Unfortunately I have not done a good job keeping up with technological advances lately. I am intrigued by the systems that sense the amount of slippage on each individual wheel and redirect the torque to where it does the most good. I will sooner or later find something to read that explain how that works. I think the ultimate solution is a system that drops a set of tank tracks over the wheels when necessary.

Those are referred, most often as AWD. And they are THE BEST at on road traction. Computer controlled and can send power to each slipping wheel independently in some of the more advanced cases. They, however, are complicated mechanically and are not as robust as 4wd. Other than electronic controls and some auto engagement add ons, 4wd is pretty much the same as it was in your Dad's old Jeep, mechanically.

The Yukon XL Denali I'm driving now, Escalade and others are AWD. No low set though

There is a tank tread system for trucks! they actually bolt onto the existing lugnuts and are used up in the arctic. See here :

Re: AWD, I didn't mention that I used the AWD lock on my Pilot towing in muck, not anything uneven or steep, but but it locks the four wheels and make a noticeable difference.

Could you post a larger version of your avatar. I would like to see what your setup looks like.

Given the type of camping we do, it is 4x4, hands down.

A big advantage in the more scenic parts of the West, is the ability to drop the Bambi in its campsite, and then take off in the truck for a day in the back-of-beyond. Many of the roads are unsuitable for anything but 4x4.

A pick-up truck with a cap (canopy) on the back adds significantly to our gear storage capacity.

I also feel that Easterners sometimes get a yen to explore the western National Parks, so it might be good to keep your travel options open.

On the other hand, the people at Can Am in Ontario where we bought the Bambi thought that a big old Chrysler sedan was the ultimate tow vehicle. On pavement, I imagine.

Just to add a bit of a twist to this thread,

That viagra commercial with the cowboy hauling horses gets his 4X4 (straight axle, locker front hubs) stuck with one wheel spinning and has to resort to two horsepower to pull thru the mud hole.

Did that work because he gave the horses Viagra?

That's not what a locker is. He had 4wd with open differentials.

No, it's not real. He didn't take Viagra either. He was out, walking around on two legs only.....no kickstand!

I had a Camaro once with a light rear end and limited slip differential. Worst car in the snow I ever drove. The limited slip pulled me out of a bad spot once when I got one wheel in a soft spot and one wheel up on the hard gravel. But in the snow, we lived in a town with a lot of side hills. Both wheels break loose and the rear end goes sideways. Not a good feeling when there are parked cars or traffic on that side. Yes, it had a bit more pull. But not as much control.
