Have you driven both types? When I was first looking for a 1st gen., I had the opportunity to test drive a 22re 4runner first and then the 22rte I ended up purchasing. There is a major difference in power. The '86 will do fine on the dirt roads and will be a lot more powerful when you step on it. I'm a little bias since I miss my 22rte runner. Also, check out Jeff's site to see what he has done with his little 22rte truck.
