For our front under the driver's seat bay electric fuse panel, this would be pretty good bulk buy.
It would be better, to go and read the size of the fuses in your specific coach. (5A, 10A, 25A - etc.) - then order just those sizes.
Also note if you have not plastic backed fuses, a bit larger units with a metal cover (In our coach anyways.). Note size of those, and get a few extras. If needed, take a picture, and visit a NAPA, or auto store, and they should be able to help you.
With my eyes like they are - yes, still a beautiful blue with a very occasional flash of brilliance ---- BUT I DON'T SEE HOW I USED TOO!!! I took pictures of each side of the fuels label legend, uploaded to the computer - makes reading much easier!!!
Best of luck to you,
