Question 1: Any idea where the trailer fuse box is located? I've read I should turn on the hazard lights and listen for the relays...will do if no one knows the location!
Question 2: Any thoughts on what might be causing the fuses to blow?
You've stated what make and model of coach you have but, not the chassis. If it's a Freightliner, there's a few places that the trailer plug fuses can be. On ours, which is an '04 Itasca Horizon, 36GD with the C-7 330HP CAT, they're located up underneath the left rear leuvered panel for our dash A/C access. The panel has to be lifted to gain access.
On other Winnebago's, it's in the shore power compartment, sometimes behind a removable panel. The smart thing to do for you would be to call Fleetwood and get wiring information on your particular coach. That will lead you right to where it's located. And, as far as WHY you blow fuses IN THAT SYSTEM, every now and then, there' can be all kinds of reasons. Once that comes to mind is, some of the strands of wire, from each input, can become un-attached or, un-clamed from inside the back of the trailer plug and, can actually come in contact with each other on occasion which, in certain circumstances, will blow a fuse.
There's lots more potentially bad spots in wiring that will cause that situation of blow repetitive fuses. You'd have to trace that particular circuit to find out why.
