Looking for a resource that lists, among other things, towing specs for
used trucks or larger SUVs...

I've tried KBB and one or two other suchlikes, but no luck. I'm looking
for a decent mid 1990s vehicle that can tow 8000 pounds on a trailer
fairly short distances...maybe 25 miles one way. I know about Chevy
Suburbans...but I'd really prefer an older pick-me-up.

Might anyone suggest an on-line site that displays these capacities?

Thanks!
