Other than the gas milage I can't think of any. We just upgraded from a 95 4runner that we had for 9 years but the boys are growing bigger so when the head gasket blew in the runner we decided to get rid of it and get an 80, we couldn't be happier.
So far we have installed OME j springs and shocks witch give about 3" lift and bfg 315 mud terrains. We have wheeled it at Hollister and into gate keeper and Wentworth springs at the Rubicon and I think does quite well for a stock truck with open diffs. Very comfy and a lot more room than the runner.
