I am one of these die-hards that absolutely WILL NOT use a truck stop (and my truck is diesel).
I have a long bed, crew cab, diesel dually and my fifth wheel is 41.5 feet long. Added together, the total length is right at 60 feet.
I use NORMAL gas stations that sell "auto diesel". First off, diesel is very confusing and each state seems to run on a different set of rules.
Off-road diesel, road diesel, commercial diesel, taxed diesel, non-taxed diesel, which pump to use, what if I fill up with the wrong one?
Pumping diesel from a normal gas station pumps, along side the "gas" pumps eliminates all the confusion. This diesel is set up and priced appropriately for non-commercial or highway use for private vehicles..... THAT is why I use regular, normal gas stations that sell diesel.
So, that puts me in the same category as you, navigating a very long rig into normal, every day use gas / fueling stations.
It takes a bit of planning to do it and do it successfully. I always look for open, larger service stations with fueling bays that will permit easy in-and-easy out. Granted, sometimes I have to wait to get to the diesel pump because the ONLY diesel pump is between two regular gas station pumps at the end of the outer island. But, I sit and wait until traffic moves out of the way.
This is when you learn REAL fast how inconsiderate people really are. They will park their cars at the gas pumps and go inside and spend as much as 15 - 20 minutes inside. Meanwhile, no one can use that pump.
So, you know what ... I don't give a rats A** if my 60 foot rig is blocking everything moving on the lot. If the inconsiderate SOB would simply come out and park their vehicle in a normal parking spot, I could move forward and get out of the way. Besides, once in some of these positions, it can be impossible to move until THEY move.
I'm at the point where I simply do not care any more. People are pigs and they will not give others a break, so why in the H*** should I give a break any more either. I really don't care any more. I use to, but no more. So, I am only as rude as the inconsiderate slob spending 15 minutes inside the store. Move their vehicle and I can then get out of the way .... so don't blame me!
THAT is how I do it now. And I don't feel bad about it any more. People want to be rude and inconsiderate and selfish, well, when my 60 foot rig is blocking everything from coming and going from the service station.... yea! I just point to the car sitting empty at the pump I'm attempting to get up to!
