unless you need a 1 ton, Id go with the 86. Its got a newer engine, and probably less wear and tear on the body. If theyre both single cabs, I dont think the ride will be much different. If the 82 is having trans issues, you'll have close to $2000 in it anyway.
My 86 1 ton crewcab rides alot better than any of the other trucks. 1/2 ton or 3/4 ton, but single cab verses single cab, I dont think it would make a noticable difference, but Ivw never had a srw 1 ton singlecab either.
