With the exception of a very few old secondary road stations, I've never seen a station canopy that could not accommodate the 13'6" legal maximum vehicle height.
Our experience has been somewhat different. We require diesel and, many times, the available stops for us on secondary roads that can accommodate our height are few and far between, and some of those that can are just so close in roof height we would only attempt it in an emergency. When we are traveling in areas with little truck traffic and sparse population we plan our fuel stops in advance. This may involve detouring a few miles to a major highway with a truck stop - not a huge problem unless needing fuel sneaks up on you. This may be a hidden advantage, also, as buying diesel from an isolated mom and pop with little diesel volume, I have read, is something to avoid anyway.
