Any RV'ers around here?
We call the tires "Chinese bombs" And 4 6volt Golf cart batteries is the ticket to long power use. Two in series to make a 12volt bank, twice, then the two banks in parallel to double Capacity. Power Will last a long time.
We had a 4k generator, but didn't need to run it much at all with the 4 deep cycle 6v's.
The kids ran their TV and an X box with an inverter, we used the lights, stereo and all for a 3 day dry parked weekend and those batteries did a good job of keeping up with it.
I had two sets of batteries that I could connect or disconnect with a rocker switch on the dash.
While driving to where we were going the motor would be topping off the charge of both sets, and once we got where we were going I would disconnect the engine set from the coach set via the switch.
That way if one set got drained too much I could connect them back together again and have starting power for the generator or motor either/or.
I just can't say enough about having things set up so that you never end up with everything dead, but in our case 99.9% of our camping was out in the middle of nowhere with no services.
The EV series of Honda gens are really nice to have also, but they sure are expensive little suckers.
It would have been nice to come back after a day of dirt bike riding and have a solar unit building the batteries back up all day though.
