30 amp fuse replacement

I've made a list of suggestions from this forum that, one-by-one, I'm doing to my 3124kb. Just got around to replacing the glass 30 amp main fuse at the battery with a blade fuse. And what did I discover in the process?

Well, I followed the line from the 30 amp glass fuse and in a short distance found ANOTHER 30 amp glass fuse which led to the electric tongue jack! Going back to the two wires coming off the positive battery terminal, I found the lead from the TM going direct to the battery with no fuse at all.

At least I had a well protected tongue jack.
