good batteries, low electricity use throughout the rest of the coach, and the occasional use of the generator.
Thanks,

might need more details on what fridge you have.
unlimited answers to that question... the variables are how long do you need to boondock? and how often would you want to run a generator? and the biggest question of all, how much money do you want to spend?
I have an original norcold fridge(110v and 12v). and I cannot get more then a weekend out of my 65 watt solar, 2 6v golf cart batteries. LED lighting, I can barely get 24 hours in some cases. I have learned that by stuffing it with ice, it will significantly keep the draw down. I have a few other things I want to do, just have not done yet. the main solution for me is to replace that fridge with a propane one. with my setup, I know my boondocking at that point would be limited back to how much black water I can deal with, and not battery life.

It will use less current (battery) than the built-in inverter, and will also keep the frequency at 60Hz (protecting it from any Onan frequency variations).

I have a Norcold, and the buzz-box has been replaced with a Progressive with a charge wizard.
Thanks for all the replies. You guys are great. A lot to think about; not the least of which is, how badly do we want to dry camp?

We dry camped a couple of times in the first few years of ownership, with the original all electric Norcold. I used a small portable generator to keep the batteries charged (first a small Coleman 1600 watt and then a Honeywell 2000 watt inverter generator). The small generators used considerably less gas than the Onan but still made noise. At the sand dunes, it was no big deal, but at Quartzsite, in the Ham fest area, I got the hairy eyeball from a lot of the other people with solar and heat absorption fridges. Since then I have replaced my fridge with a 3-way and added a 140 watt solar charging system, among other things, and I no longer worry about it. We dry camp frequently.

65W of solar isn't gonna do it. You are only pushing 4-ish amps to the battery, and given about 3-5 charge hours per day, you will not replenish your charge totally.
I ran 2 days then about 2-3 hours with the genny to recharge, but the PD9460 puts out 60 A while charging. This was running my furnace, and dropping the batteries (2 GC2's) below 80% which is not good.
Run the genny every day to keep your batteries from dying an early death, or add about another 300w of solar. That refer is an energy hog.
