Ive had both for decades. I like the Bronco for interior roominess and ride. I think the Jeep is a better 4X4. The current sky-high prices for the Bronco are not reflective of its off-road ability. Though ours are not modified at all, both have lots of aftermarket mods to improve the vehicles in almost any way you'd want.
Yep, I have one in a '66 Ford F-110 pickup. I don't even know what the F-110 model is, but this pickup must be a heavy-duty version of the F-100 series, because it has a Dana 60 rear with 5-lug flanged axles ! _ _ and it has the single-speed transfer case behind a granny 4-speed with kind of a long adapter maybe 4-inches. So the single speed must have been one of the first of the "married" style T-cases.
The older Wagons if set-up properly are Very Capable in my opinion. My wife and kids were on the high-trail above the slabs between the Little Sluice box and Buck Island Reservoir on the Rubicon trail one summer maybe 1995, we were stopped taking a break, and a nice early bronco pulled up. It is always fun to visit with other wheelers, and he had a pretty trick Bronco. He took the high trail so he could drop down through what is called the Big-Old-Sluice which comes back into the side-hill trail down the Slabs near-to Buck Island reservoir. He pointed down the slabs to the rest of his group, which was 3-older Willys Wagons. I never did get to see them in person, but they moved right through with no hold-ups at all.
If I remember correctly, they were from Utah.
The benefit of the Bronco is it's short wheelbase over the Wagons. The metal tops are heavy and cumbersome to remove.
Looking back over traveling that Rubicon trail from 1983 to 2001, some of the most impressive rigs for agility, were the late '90's Cherokee's with the Long-Arm kits and Terra-Low gears and ARB air lockers front and rear. They had Articulation like Spiderman.
I'm IN for the Willys Wagon !
In the above photos, it looks like the wagon has a pickup 4-speed trans with the long staff !
I know where an early Bronco is setting, noticed some of the rear lights were missing, I thought about checking it out further
before I bought my 58 CJ5. I'll try to do that soon and let the members know in case someone might be interested.
