So many factors come into play with MPG which is why most RVers never even bother. Terrain, weight, wind, traffic, speed, etc. Some fella at a gas station once asked me what kind of mileage I got on my class A. I said; it gets great mileage for an apartment.
We've been tracking our travels with a spreadsheet that goes back to 2007. It includes, miles, travel hours and MPG for the day. It then pulls the data over and runs a long term average. I also make notes on driving condition as a strong head/tail wind, was the drive hill with a lot of elevation gain/loss...these can have a significant impact on MPG (I've had it vary from 7.5mpg up to 16.8mpg).
For planning a long trip, I generally assume a bit less than the long term average. This gets used for general budgeting purposes.
For daily driving, I can get a pretty good idea of impacts on range based on the wind forecast and how hilly the route is. This is useful to determine if I need to fill up before we hook up.
This SOUNDS way too much like work ! ! ! Get in and rock and roll..... I know my truck, I know when the 48 gallons is getting low, and if traveling to parts unknown, I usually scope things out ahead of time on goggle maps around the mileage I usually need to refuel . . .
