If he's just going to trail ride and take it to the lake, why not get a more common '87 4Runner with IFS ?
Save the solid axles for the serious guys that need them.
Also, I swear to god the cap on the 4Runner weighs 300 pounds. I can't even get it to budge, I need at least another big dude to help me, and even that is a pain in the arse. With my girlfriend we have devised a lever and plane system to remove the cap with minimal to-do.
Needless to say, once it's off it's off for at least a week.
