Battery Upgrade
So, I just bought a new 5th wheel toyhauler. It currently has a single 12v battery. I want to seriously upgrade the battery capacity. I had 2 Costco 6v golf cart batteries in my last rig. I think ...

Something else to throw in the mix folks.
Should their be a 300Amp fuse between the inverter & positive post?
I have zero gauge between the positive inverter post and the batteries BUT that &^#$ fuse heats up! Not hot enough to burn but hot. Not sure what I'm loosing thru it. Ideas?
Absolutely there should be a fuse or circuit breaker there. If you think the fuse is getting hot, consider what a short circuit would do; several thousand watts being dissipated is no laughing matter.
You could measure the voltage drop across the fuse under load pretty easily with a decent voltmeter. It might also be good to check that the connections to the fuse are good and tight and clean; quite possibly some of the heat isn't due to the fuse itself, but due to a resistive connection there. (That would incidentally also tend to cause the fuse to blow earlier than it otherwise should, since it's basically vaporized by heat when it blows.)
