I am curious to know what I can tow with my service truck. Its a 1994 Hino FB with a @200hp turbo 4 and a heavy allison auto. The dealership had no idea. They said the tranny was off a bigger truck and could handle a lot, but didn't know about the engine. I want to pull a tandem pintle trailer with a 5000# mini or compact TLB(haven't bought it yet) Any thoughts?
