I have not re-geared. I run 35's with stock gearing, ARB up front and 4x4 Labs in the back with spare and 3 full 20 liter scepter gas cans. The trailer weighed in around 3k. On the trip down to Moab area from Salt Lake City we achieved 13.8 miles to the gallon and the way back we got 13.3 mpg. We were doing 70 where allowed and 65 the rest of the way. I was surprised. Every day driving is around 14, so I expected around 11.5 to 12. We had a great time in the La Sal mountains.
