Mike, I towed my toy hauler this weekend and had high trans temps. I already have your cooler and now a SCIV and the trans temp. hovered around 235 while towing yesterday. I was driving in t/h, outside temp around 107*, driving around 68 mph with my trailer empty, except food and clothes, no bikes, water or anything else. Trailer might be 9k. Any other ideas on how to keep it cool?
