Hi Rob,
Jerry, did a little post on fuses a while back -- you might look at his files !!
NAPA auto parts stores, have a very nice fuse block for RV,s with a rubber cover, and you can order the fuses, in any amperage you want.. (no LED though)
Wish I had kept the part numbers, but they are at my cabin -- 550 miles south !!
Good day, Bill H........
