Good truck with auto tranny cooler installed.(2.8 liter 4 cyl).<br />Frame mounted Reese hitch towing an 18 ft bowrider w/140 OB. I don't use OD on the tranny until cruising above 55mph. It's a single axle aluminum trailer without brakes.<br />Does anyone feel this a bad idea for any reason? I live in Florida and the hills are few and small at best.
