Me, I'd move the tank to a more accessible location.
Whether you do that or install (and bury ?) an extension/filler hose, it's all a short hassle, right ?
But with an optimum tank location, refills & driveway should be less of a long-term concern.

When I had propane years ago, it was over 100' from the truck and that wasn't a problem.
All the flex hose (house and 2 separate shops) looked the same to me (and all got buried).
If you do a filler-extension, make a map of its location.
