Assuming my transmission gets repaired, I plan on towing my boat. I see cars in tow behind Sprinter based RVs. Some heavier than the approximate 2,200 lbs. for my boat and trailer. Is it necessary to add an external cooler for the transmission? No one I've asked so far even thought about it and they are doing just fine. What's up?

It should be fine with the factory cooler assuming you are under GCWR, which you should be with a trailer that light.
But... When the transmission took a dump the first time, did the shop say it appeared to be heat damage? Or some other cause?

Cooolers are cheap, transmissions aren't.

I towed my boat only once last year for about 20 miles to run up a grade on the Interstate to see what kind of pulling power I had. I've owned the boat since 1988 and the trailer has no brakes. I've towed the boat with a Ford LTD station wagon, two pickup trucks, a RoadTrek and now I'm thinking about towing with my Sprinter Class C. I was told that it might be a good idea to add brakes to trailer as I have to negotiate a number of 6% grades. Easy enough to do, but I was just wondering if the external cooler was necessary. My transmission failed, but not due to unusual loading. It's in the shop now for a third re-build in a month's time, maybe they'll just give up and put a new transmission in. No one seems to know why all the transmission oil pumped out on the ground all at once.
