I have an 03' SR5 V8 (TRD package) and I have added the RoadMaster Active Suspension kit. My truck came with a distributor added tow package (Class III hitch and 4-pin connector) instead of the the OEM tow package which includes a transmission cooler. Mind does not have the transmission cooler. I am getting ready to pull my motorcycle trailer from Alabama to Kentucky for a rally next weekend. The trailer is a 5 x 10 (enclosed) Wells Cargo CycleWagon. It has a curb weight of 1120 lbs. and GVWR of 2200 lbs. The trailer is a little lower (6' 11" ground to top) than regular trailers and has a NoseCone front end. The bike I haul has an approximate weight of 650 lbs. My question is this? Since the combined weight of trailer, bike, and gear will be slightly less than 2000 lbs., will I be okay w/out the transmission cooler? I have asked several service managers at Toyota dealerships and they say "pull away" and enjoy. However, a mechanic friend of mine said I definitely need a transmission cooler even if I pull a 300 lb. open trailer. I can order an aftermarket unit but don't have time to get it installed and I pull the trailer so infrequently, I hate to spend several hundred $$ if I don't really need it. I know there are many members of TS who have knowledge in the area of towing and I would appreciate any advice. I would assume Toyota designed the Tundra to have some towing capacity w/out the optional tow package but I could be wrong--

Thanks in advance----
