The solar part sounds really intriguing.. That might be a way to go when I graduate from being a newbie to advanced RVer.
What do you have in the way of batteries and how do cloudy days affect maintaining the battery charge level?

Pat,
Aaron is right, way back almost before I can remember, the 3 way fridge was common. The last time I saw a 3 way in a TT was in the '70s.
An inverter is nice to have, but you need something to keep the battery/ies charged. Using your truck to charge the battery, is like using a very expensive generator.
My 2 cents worth on the subject of batteries and maintaining them, based on how we travel and camp. We don't watch much TV or use 120V appliances when we are traveling. The biggest power draw is the furnace when it is needed and your 12V lights.
First thing I would do is replace all the 12V lights with LEDs. We like cool white bulbs as it makes easier on the eyes when we are reading. Next replace the 12V battery with 2-6V golf cart batteries wired in series. That will give you around 50% more reserve power.
Now I would add a solar system to keep batteries charged while we are boondocking, which makes is a big part of our travels. I started with a 100W panel and a 30A controller, which was great in Alaska, but I'm adding another 100W panel to give the system a boost when it's overcast. For any 120V appliances that we might use we plug the inverter into a 12V socket that I wired specifically for that purpose.
Finally I would add a generator, for heavier 120V usage (A/C to cool down trailer when we are boondocking) and them rainy days that rarely EVER occur. :-sad- My Yamaha generator is 11 years old and has around 100 hours on it, the majority of those hours were from camping at a race.
It took us awhile to get it all figured out and we all have different power requirements, so you are going to have to do some experimenting.
A great place to be working those details out is in your driveway, that way when your battery goes dead from the furnace running all night you can be nice and warm in the house. Once you get things figured out for your type of usage, you can cross the counrty and never have to hook up to the grid.
