I need some info and guidance for the following project. PROJECT: 1. I plan to install an auxiliary battery in the cargo bed of the truck, from which I’d be running a 12v to 110v inverter (1000watts). The idea is to hook up the 110v shore power line of my camper (which draws a max of 750w) to the inverter. Inverter specs state: Input power (max at full load) 1200 VA Input current (max at full load) 93 A 2. The power source to charge the aux battery would be: A - Solar panels during the day, and B - the truck’s alternator during a few hrs at night, via a DC-DC charger to be connected to the main starting battery. 3. To hook up the aux battery to the vehicle’s 12v system (2B, above) I’m considering one of three wiring options: A - the 12v power at the factory installed towing hitch, coming from a 30amp fuse at the front’s Fuse Box. B - the 12v power at the factory installed outlet in the bed of the truck, coming from a 20AMP fuse at the front’s Fuse Box. (Specs state: max load 20AMP) C - New wiring running from the main battery to the bed of the truck. (Protected with an 80 amp fuse) 4. INFO NEEDED: A - How thick should the cables be to handle the inverter load? B - what would be the best alternative in choosing the source for the connection in #3, above? (Alternatives A, B and C were listed in the order of my preference, based on ease of installation.) C - With alt.4C, above, at which end should I put the 80 amp fuse?
