IT's got about 270K mi and is well maintained. I some times tow at least one motorcycle weighing about 460lbs and would like to be able to tow two bikes, about the same weight for a combined total of nearly 1000lbs (+trailer and diamondplate deck).

Do you think it's necessary or recommended that I install a supplemental cooling system (something that I think att to the radiator) so I don't burn out my tranny?

Any recommendations as to what to get, where to get it, and how much I can expect to pay (I can probably install it myself) would be greatly appreciated.

Thanks!
