You know, every gas station has tractor trailers that enter it to deliver gas. Perhaps you are more cautious than you need to be.
Real good point. But where the tanks are isn't necessarily as tight as getting into the pumps. And then I've found a lot of the time the problem is where the cars park that aren't getting gas when it's a a really small station.
DRSMPS there are truckers GPS units that are supposed to be more big vehicle friendly, bridges, fuel, etc. If you've got a 5 hour range you should be able to look at your trip for the day and pick a larger town, then use something like Gas Buddy to find what stations are in that town. At least one of them will be relatively big vehicle friendly, farm and construction trucks are everywhere. Looking for diesel is a good idea.
