When climbing hills the OD needs to be turned off. We turned the axel on our trailer over and run 15 inch tires and wheels on it. We put a transmission cooler and fan to help push air thru the jeep. We have climbed steep grades our Rpm is 3000, highway 60mph and rpm is about 2800. We live i Washington State and have gone on many passes around Mt. Rainier with no issues. We average about 12 miles per gallon when towing.
Yeah, I think the 3.73 gears are the problem on mine. I'm actually down at the coast right now, pulled my 17FQ down here with the Jeep using the back roads. A couple hundred miles and a fiv hour trip. It did okay, around 11mpg with 33's at 55mph. As long as there was no headwind I could stay in 4th at 2300 rpm but the slightest grade or headwind had me in 3rd at around 3400rpm.
I've got almost 30 nights now in this 17FQ, really enjoy it. Have done a lot of different mods so far and keep finding ways to make it more useful. Even changed out the wheels and tires with 15" versions with a higher weight capacity and didn't have to flip the axle. Probably the best mod so far was an 8" Cool Gel memory foam mattress. Very comfortable.
