Brettmm92,
The fuse should be as near the battery bank as humanly possible. It is a catastrophic failure fuse.
Before welders were "plug in" devices, batteries were used for that purpose. You can imagine what dumping 2600 watt-hours of battery in two seconds would do to an RV.
It would be insanely hot, so the fuse is there to protect the wire from melting and catching everything around it on fire. Anyone who goes without a fuse invalidates their insurance, and is taking a HUGE risk.
I find it much better to be a live chicken, than a dead duck.
I am NOT a fan of panels that have to be set up and struck down every time the RV is moved. It is far better to simply add an additional panel to the roof. Then you even get charging while trundling down the road. Remember the panels are the cheapest part of all this tech.
