Hi Mote. I see you are in West-By-God, and in my opinion you will not be happy with the performance of a 3.0 Ranger with a 17 foot trailer in the mountains. I tow a 16 ft
casita with a 4.0 Ranger (auto and 3.73 gears) and consider it bare minimum for anything but Kansas....it's all it wants. Imagine that your
Burro would be even more of a load. Auto tranny and 4:10 diff ratio will help but again, wouldn't want to work that hard. A trans cooler and WDH would also be required, unless you beef the stock suspension considerably.
I am going to Danville VA for bike racing this weekend and dread the pull across lover's leap on US 58.
