Exactly. 5.29's are the proper gear on the 4 cyl for those tires. Some folks are even running that with 33's. They came from the factory with 4.10 for the 235/75/15 and 4.56 with 31's, but many say 5.29 is as low as you want to go and keep your pinion strength. Would I DD one? Absolutely. Great little trucks and I've owned 2. Not powerhouses or big, but good compromises. My '91 got around 25mpg but it was stock with a lockright rear and 30x11.5x15 TSL/SX. It all depends on what you want. If I didn't have the cash I have sunk into the K5, I'd do toyota again in a heartbeat. However I'd hold out for an '85 or later to get FI. Actually '85 was the perfect year, the only one with FI and Solid axle. The perfect for me would be an '89 to '95 since the interior, tranny, rear axle, ect are much nicer. SAS swaps are very common on these years and bring up to being a nice toyota.
