I have an idea that I haven't seen discussed before.
Objective: Charge the house battery(ies) during extended boondocking trips.
Solution 1: Solar – Expensive, not enough sun in Seattle (this year is an exception)
Solution 2: Inverter Generator – Expensive, noisy, theft, fuel can
Solution 3: 12V wiring from truck – slooooow, too much voltage drop from alternator to camper battery.
Solution 4: Onboard welder with 120VAC outlet – expensive, basically another alternator with a different voltage output. Welder would be nice though.
Idea: add an 800-1000W inverter to truck and use an external charger or the house charger to charge the battery(ies). Running the truck every couple days for an 1 hour or so to charge the batteries would not be a problem. I like this idea because it would be simple, inexpensive and does not involve a lot of extra equipment.
Would this work? Any thoughts?
