A short story and then a question. A friend is towing a super-lite 5th wheel and has a gasoline engine. He was told by the RV dealer that 11-14 should be his mileage. Now that he has gotten home he and momma did he REAL math and got 8.1 over 2600 miles.
What he is sad mostly over is his truck only has a 26 gallon tank. Anybody have any experience with installing an upright auxiliary "gasoline" tank in the bed. Neither of them are thrilled with stopping every 160 miles to refuel. Many thanks to all.
