Truck- Trailer combos and vehicle performance.

I gotta tell allya'all* seeing people answer the question asked without straying off course is refreshing. I posed the same question on a Facebook page and for the most part, got some very useful and on target answers. However, there were those few whose reading comprehension skills prove they are not smarter than a 5th grader while trying to make you feel like a 5th grader. Here are a few of the things they pushed that did not remotely address the question of comparing the digital read-out to manual calculations.

-7th grade math lesson on how to calculate mpg
-manual calculation of just one tank is meaningless
including all of the variables of what effects tank level when filling up
-if you are worried about mpg, you shouldn't own a truck & 5th wheel
-If I had to think this issue I would just stay home and ride my bike,just saying
-Doing the math if you have a 36 gallon fuel tank math wisw it would be correct (I don't even remotely understand that one. What is wisw?)

Anyway, thanks for all the on topic responses.

*ally'all = it's just a Texas thang.
