I can tell you, these little Toyota trucks are real work horses. Back in 1978 my dad wanted a truck. He decided on a Toyota. At the time I think all they made were small trucks and it was simply a Toyota truck. Anyway, this little beast had a 4 cylinder engine, automatic tranny, regular cab and long bed. Believe it or not, I think it was a 7 foot bed. Anyway, we had a limestone mine about 10 miles from our place and dad wanted to get some stone. We took that little truck down into the valley where the mine was. This is a mile lone hill down to the mine. We got limestone and proceeded to the scales to see what we had to pay. That little truck had 2,800 pounds of limestone in the bed. We weren't sure but decided to try it. Dad let me drive (he was brave that way). Well we started up the hill and that little truck just went and about 3/4 of the way up we hit 4th gear. I couldn't believe it. Anyway we got the load home without an issue and I shoveled stone for the next few hours. So, yeah, these little trucks are tough. I'm thinking about a Tacoma for my next truck and am very interested in how they tow.
I see guys up the road getting firewood now and then in a little Toyota. They always stack the wood to the top of the roof. Safe to say, they will haul anything you can fit in the bed.
