There is another thing to consider. First, Jerry is absolutely correct about the need to carry spare filters. At the first sign of the engine shuddering or slowing down you need to find a truck stop and be able to access the fueling island.
You have not lived until you have run your bus out of fuel. I am not suggesting you have run the tank dry, just that you have clogged filters such that fuel stops getting to the engine.
Can you imagine doing this along side of the interstate?
When you change fuel filters it is imperative that you fill them to overflowing with fresh fuel (hence the need to be near a source of fuel). Depending on your coach and the equipment in your fuel system it may take more fuel than you can carry in a gallon jug. My old Liberty had two spin on filters and the big Racor Jerry talked about. If you have never changed your filters or are unfamiliar with the process there is an article on this under information sharing.
