We just traveled 2300 miles (first long trip) towing our NC 29FKS (appr. 12,000 lbs) w/'99 7.3 SD stock. It seemed like the floorboards and firewall were extremely hot all the time but temp. gauge never got high, nor did the truck seem like it was having any other problems. Ambient temps were 80s/90s most everywhere but I don't think that would cause the degree of heat we experienced. Am I being neurotic about this heat thing, or is our new "3 exhaust a big contributor to all the heat? I've read a lot on this forum about the necessity of the bigger exhausts and air filter upgrades when towing. We also noticed that just going over 65 mph really jacked up the RPMs. Do most of you run about 65 regardless of the 70 speed limit areas?
