I've done ok over the past few years full timing towing a toad. What I found of course with a MH towing when looking to get gas is to look AHEAD BEFORE pulling in analyzing if there is a direct exit to get out.
I stay away from gas stations where the pumps are perpendicular to the store and they have customer parking along the front of the store. These are a kiss of death when you are that long.
I don't use them solely for fueling but I know I always can get in and out at Loves. they keep the pumps WAY away from the store front and gas islands are real wide.
I try to do all my fuels stops on the interstates where I can 'see' the station from the highway to make my decision whether I will fit before I even exit.
I no longer will exit to a gas station that is not right on the intersection where I can see it.
Some of those way off the exit ramp, when you get there not only can you NOT get in to the station you can't even find a cross road or parking lot to turn around to get back to the interstate. I have had to drive miles before finding a place to turn around with those.:(
