Critique proposed solar battery upgrade

Thanks for all the replies so far!
Running the fridge during the day would be the cherry on top, but isn't a deciding factor. Not ready to make the leap to residential fridge, as we do at least 2x trips a year where we'll leave the trailer at a nearby campground for a month on an unserviced site and do weekends - that's when LP is really nice, no issues with the fridge in the past few years.
Lithium Ion is a nice idea, but would at this stage completely obliterate any 'business case' justification even I could come up with, and I've made some whoppers over the years to convince the boss that I really need what I really don't need ;)
I guess the bottom line question after all this great input is, is there enough of a reason to switch from FLA to AGM given what I'm doing? Right now, my biggest worry is watching the inverter bottom out at 11.4 when running the coffee maker, and it bugs me... strange, I know, but different strokes for different folks. I have a 2k Yamaha genny, just don't like running it if I can avoid it.

FWIW I had my garage fridge (fullsize residential) running off my solar rig (about 200 watts and 450 Ahrs of storage) for a week and the batteries were fully charged at the end of the week, the smaller residential fridges typical in RV's should do even better.
