If you are going to boondock... Sooner or later you WILL come up short on battery power.
So you NEED a way to recharge them on site, without quitting and going home. Lots of ways to do it. They all have their pluses and minuses. I have and recommend a generator.
My reasons are it can give me plenty of power on demand. Rain or shine, night or day. It is like being plugged in to shore power.
In addition, all of the AC stuff such as microwave and Air conditioner TVs outlets etc, can all be powered without getting an inverter.
Solar and jumping off of the TV battery can recharge your battery, but will not provide the on demand hi power that a generator will. Each of those proponents have vocal fans of those methods, and I believe they have their place... But if you can only do one, and want it to be the most useful... Get a generator. Your wife with her young child will thank you.
On a side note: About a week ago we had a pretty good storm in Phoenix. 3 transformers in my neighborhood blew. Massive power outages everywhere. I hooked up my generators to my TT, and ran a electrical cord to my house's fridge. We spent a comfortable air.conditioned night in the TT, and did not lose any food. Many of my neighbors were panicking and scrambling, some trying to get a motel.... Well a lot of them were without power as well.
Having a generator can really save the day... And is nice to have when camping as well.:B
