I lived in Saudi Arabia for 6 years and had a 1FZ-F with the H151f manual 5 speed, part time 4wd, etc. It was so far my favorite vehicle. I had stock diff gears and was running 285 75 r16 tires. Even though the carby version of the 1FZ was a little lower on power than its injected sibling, I never really felt the need for more power unless it was time for a tune-up. I loved driving that thing through the dunes. I used to lead multi-day desert trips so we were often loaded down. I haven't actually driven an auto 80 series, but I feel like with the manual I could make really good use of the available power and torque. It wasn't a rock crawler, though, and there were a few times I wished for lower gears crawling through rocky washes and up rock steps. I'm a little biased, though; my "car" in the U.S. is a 1st gen 4runner with dual cases so about 240:1 with the turbo transmission and 5.29 gears. Even so, I would have a manual in another 80 series in a hearbeat. If it hadn't been COVID times when we left last spring, I may have tried to bring it back to the U.S.
