Whats pulling your RPod

Very interesting. We have the same setup and have been getting 17-18 mpg.  That's according to the car calculator.  Of course we are driving slow trying to keep it 58-60.  But have gone up to 70 when road conditions are perfect and wind is on on backs.

The trailhawk optional engine is 3.2L V6 24 valve.  It is 271 hp and 239 lbs torgue.  We have taken our 180 by accident over appalachian mountains where there are signs warning no trucks and she did just fine pulling the RPOD.  Having the break controller helped on the way down and did not even feel we were being pushed

It isn't just the engine. It is also the transmission, differential, and final gear ratio that affects mileage. Aerodynamics also play a part. I tow our R-Pod with a 2010 Nissan Frontier Crew Cab LE 4x4. One thing that will make a big difference is on uphill climbs. If I try to maintain speed and let the transmission downshift so that the RPMs exceed 3,000, I will get single-digit mileage. Turning cruise control off and turning overdrive help as cruise control will downshift the transmission and I will find the engine hitting 4,000+ RPM.

One other thing that can help is to get a wind deflector such as PurpleLine USA's AeroPlus or Icon's AeroShield. Either one when set up will help. Limiting your speed to 60 mph or less makes for a more relaxed drive and for better gas mileage. Air resistance does not increase linearly with speed but exponentially.

That is what I do. I have a small notebook in which I note the miles traveled for that tank full and how many gallons it took to fill the tank. The Frontier does an average mileage. The Torque app does an instant mileage. The best average though is the old-fashioned calculation, either for one tank full or for several tanks full.

Picked up our new R pod on 3/1/18 and had to go over Wolf Creek Pass right out of the shoot.
