RE: Average mileage of different engine setups - Latitude 28 - 09-09-2019

   
Took this picture three or four weeks ago after filling up in KY traveled North through IL & WI towing a Honda CRV.  The mileage settled down to 8.13 for the rest of the trip.  Coach weighed 49,500 CRV toad at 2900#. 

The way I look at the mileage is pounds per gallon.  Take a F350 Power-stroke dually...empty... say 7500# at 17 MPG .  That works out to 441# per gallon.   Our coach at 52,400# and say 8.13 mpg works out to 6,445# per gallon.  Looking at it with that perspective we are operating some pretty efficient vehicles.  Now just for fun go figure out what a Prius would be in pounds per gallon:-)

RE: Average mileage of different engine setups - Little - 09-09-2019

Our '86 has used 2020 gal. fuel in 11,615 miles. 8V92 All western states and western Canada. About 4000 miles towing a 28' Pace stacker near 15000 lb., rest with a wrangler. Lots of passes, valley driving, not much 4 lane. Maybe 10% gen. run time as our A/C runs off the inverter, and we have a Honda inverter when stopped. Lots of higher rpm time climbing to manage heat. We don't get in a rush and enjoy the ride. We also have a Wanderlodge LX 40 with a Cummins M!! 450HP. Haven't used it much (I like the old Newell) but it appears the Cummins gets about 7-8 mpg on a trip from Boise to Phoenix, towing Hummer H2.

RE: Average mileage of different engine setups - DK on the road - 09-09-2019

Has anyone evaluated the accuracy of the dash monitor for fuel consumption vs Pump volume and odometer readings. I'm not suggesting that they aren't correct, it's that I don't understand the parameters used by the monitor to make the evaluation. My unit reads numbers much lower that what I'm actually getting, so I stopped looking at it.

BTW, I like the analysis of fuel and weight. Do the same for a Train or a Tug on the Mississippi moving barges (down stream)

New Class 8 trucks are getting so wind slippery, that they are trying to get 80,000 lbs over the road and reach into the 8+ mpg, I understand the low 7's is more common.
