Bed room slide quit working on our way home to Florida.  I of course saw dollar signs flying out the window.  Easy fix though, the fuse in the bed room panel was bad.  It was a 20 amp fuse in a spot that was labeled on the panel as 15 amp.  Someone had scratched out 15 and wrote 20 on it.  I replaced it with a 15 and it has been working but I'm wondering if maybe it should be a 20 amp?  Or maybe a slow blow 15.  Any other experiences?  I'm inclined to just leave it as is with a 15 as labeled but always open to other options.  Thank you.
