In about 3 and a half weeks I'll be towing a decent sized trailer 1000 miles with my jeep. Guessing the weight will be around 1500. Does anyone have any experience with this? How much slower do I need to drive on the freeway? Jeep is running great and I have brand new BF Goodrich Ko2 31's on it. Jeep is an 05 4.0 sport 2 door. I towed the trailer empty when I bought it and it towed just fine even at highway speeds. Trailer is a 12'x77" single axle open trailer.
