Years ago I towed with a '74 Chevrolet 3/4 ton pickup, 350, auto, 4.10 gears, 2wd, and it did the job handily. However, those were carburated engines, and the fuel mileage was not good. I do not remember the numbers off hand, but seems it was simular to your Ford van. I was towing a 24' Argosy at the time.

The mileage probably won't be much different from what you're getting, but you might convert it to fuel injection and do better. It will certainly get you down the road.

Yes I do but brakes, comfort and mileage suffer compared to modern units. We use ours on short trips when we want to look like we are 40 years late to the party............ I enjoy it but I am usually out voted by the creature comfort contingent. We do have a newer Suburban that is used most of the time.
1972' K20 Suburban w/350, 4:10 rear and GV over/underdrive.

I tow with a '74 1/2 ton p/u with a 350. It gets about 10mpg towing my '63 tradewind. A suburban would probably get slightly less with it's extra weight and 4-wheel drive.

I have been checking Craiglist looking for a Suburban, Durango or something similar. I want something that has a solid trans, engine and rear end. I really do not care what it looks like in the inside or outside. As long as it works. We will be pulling a 1960 Overlander with it. Price is the big issue.

It won't be any better, especially with 4WD. If you can find mpg numbers for the truck at 55 mph from the era, deduct 30-40% from that as a baseline (true even today).
You're much better with a modern truck just from the standpoint of reliability. I like old cars and have rebuilt them and used as daily drivers. But towing is a whole other set of strains. Start with new electrical harnesses, engine, dash, body would be my advice. Completely new cooling system, upgraded, is second. And a custom built T400 (not T350) transmission is third.
Good luck
