Over Thanksgiving, I'll be "boondocking" in a family driveway. I can plug in to their house power at 15 amps, but that will not be enough to power everything we need at certain times. Can I power up...
Consider adding auxiliary shore power cords. I have the OEM 30, a 20 and a 15 amp.
I have installed a hybrid inverter/charger that allows me to "set" the input amperage. If I exceed the setting, it will temporarily draw the extra amps from the battery bank. Of course, I can't do it "forever" but it sure makes life easier.
