Very true, I forgot to mention I also have the "Link-10" specific battery monitor, I know, a bit overkill, maybe, but being how we will stay in the middle of a desert to the middle of a mountain medow (if I can get to it) for sometimes two or more weeks, I figured it won't hurt. I only had to use the generator when in the mountains, as I don't aways get the amount of sun needed, yep there are limitations to solar as well. That EarthRoamer is some animal, but for as big and awesome as they are, they don't have a lot of living space, but I wouldn't mind cramping my style
When I picked up this motorhome ( F550 diesel) I had them add the second alternator, I knew I would need it along the way.
I'm a retired cartographer, and that would be right up my ally for sure
