Adding a second battery?
My new to me TT has a 12V Interstate deep cycle marine/rv battery, spm-24. Looked on line and it offers 140 min. at 25A and it looks like I'm could use as much as 10 amps an hour without the furnace ...

We put four Interstate GC2s in the Sahara and I also added another 100 watts of solar for a total of 200 watts. I could use another 200 watts of solar, but maybe next year.
The idea was to not be forced into expensive FHU campgrounds for every stop on our next trip which will be 3 months out west. The 4 RV/marine "deep cycle" batteries I replace were shot and wouldn't even last the night if the furnace was on. With my new setup, we can go 3 days without hookups, running the generator once or twice for a couple of hours (mostly for the hair dryer :) ).
