What's your battery setup on your travel trailer?

I just switched to lithium ion. I have one 100 amp-hour battery and a Victron monitor. I can charge it with a small a Honda generator, loading the battery at 25 amps until it gets close to capacity.

I ran the generator once yesterday, just to see how it worked, but for a three-day trip I did not really need to. (We are really cheapskates when it comes to power!)

The new battery was expensive, but I think it will be easier to use than lead-acid batteries.
