This is from a motortrend story about towing a tear drop expedition trailer behind their Cherokee on a road trip. I must say I'm surprised the fuel economy got that low even in these poor conditions.
"Because it was towing a trailer at high altitudes, the little Jeep was getting poor fuel economy — 11 to 12 miles per gallon, and the 15.9-gallon fuel tank meant we were constantly stopping for gas"
Sweet looking camper though-
