We just finished a 700+ mile tow to bring home a new Scamp 16' trailer (about 2,000 lb. empty) with our newly purchased 2018 AWD Pilot set up to tow 5,000 lb. with 6 speed transmission. We were surprised by the constant downshifting on the slightest inclines, like highway overpasses. We did not have the brake controller hooked up because we wanted to see how the Pilot did without it and it did fine, but we plan to use it in the future anyway. We called Scamp service to find out how we could make sure the trailer brakes were off. I checked hubs a few times to see if they were getting hot. They were not. It made us wonder how we would ever tow this trailer in mountains. Our gas mileage was 15 -16 mpg. This Pilot gets 28 mpg when not towing. I guessed it would get 18-ish towing this light trailer. We tried the D4 button on the gear shift but 4th gear at 60 mph revs the engine at 3,000 rpm or a little more which didn't seem like a good idea for an extended time. The Pilot seemed to do better without cruise control on if we let it slow down on uphill runs and speed up on downhill runs. Does this sound right?....because it is sure not what I expected.
