92 4runners have a drop tailgate, not a lift gate, you must have had a third gen
you are correct, it's been awhile.. my first one was a 92', last one was a 99' which did lift up.
I had to put a new engine in my 92', and then I hit a deer with it on the way to the river, then i busted the back glass out trying to fix it and sold it to a buddy who drove it all over hell.
that was the first rig i had that i really liked, i ran 31x10.50 baja claws on it, and it was an excellent woods rig. i did almost roll it once, had to have a taco hook up to the back of me, as an anchor, and another buddy hooked up to the front with his 1 ton, and i was in my rig in 4lo trying to help the program along.... all could have been avoided if i had just put it in 4hi right when i started getting crossed up, but left it in 2 wheel and slid my back end off the side.
you are right about the S10 frames, but it was never an issue in the one i had or others i was around, but it was ugly. it's not as bad as my 18' tacoma trd i just traded in, where the exhaust pipe drops way down up by the cat, that is a fire hazard design.
the first spring i owned my 18', i was running all over the logging roads in the spring, when nothing is dry, everything is lush and green, and when there was tall grass in the road, i was always smelling burning grass, finally figured out why..... it was annoying having to be so careful where i park in September, when everything is dry. can't believe they would design an offroad pickup that way.
i will say, the new colorado zr2's fixed the problems the s10's had (unless you want to run big tires, that's still a problem, haha) i haven't had the colorado long, but it is best case scenario for my needs, their suspension is unreal, and they are geared perfect for running around the hills, and don't seem to lose grunt in 4hi like most rigs do. the ride quality on and off road is crazy. i'm bad about keeping rigs, but i can't see getting rid of this one as long as it stays reliable, it's the perfect pickup for me.... it really is built for off road driving, but really fun to drive on pavement too. the only compromise there is with that pickup is some fuel economy, but it's a good compromise, i like the instant power it has. they didn't miss much detail building it for an off road capable rig. it's set up way better for towing than my taco was too
