LOL!
Too True....
I first learned this lesson in astrophysics driving a brandie new '86 Escort. This car got 34mpg easy. I put a hitch on it, hooked a 12ft UHaul on and headed out after work moving from NH to WA State, traveling with friends driving a Trans Am.
7mpg
fuel tank the size of my bladder
And Thee Darkness coming on, rapidly
at SEVEN MILES PER GALLON me......!! Crossing states the size of counties and I'm worried about fuel....I barely made it over the Hogsback outta' Vermont and coasted into the next gas station just as it closed..... The next 15hrs were a nightmare of trying to find open gas stations. NO cell phones, trying to drive straight thru the nite and northern tier backwoods towns that rolled up the streets at 9PM
At 84 miles per TANK.....
Luckily the Industrial District in the middle had some later nite stations and we bought fuel cans, carried more fuel....
We limped into Minn'DeSoda and a UHaul store, put a hitch on the TA and traded out for a 20ft trailer which we loaded to the gills. I bought my buddy's gas from MN to WA and STILL came out ahead, but better than that, we didn't have to stop for gas. 250-300mi/tank instead of 60-80
TA didn't know the trailer was there.
I trailer now with Suburbans, gasoline powered only (I despise everything about diesels, have 5 diesel rigs, hate 'em. wish they still made gas-powered tractors....) and have found that big motors rule for towing. The one I use most just gets 11mpg, towing a 24-footer or getting groc, don't matter.
So we go get groceries with something else
