Dave,
You should do the simple calculations required to ascertain your daily
usage. You'll need to connect your DVM in the '10-amp' mode and check
individual loads, one at a time (so as to not overload your meter). Make
a chart of those loads, and don't forget your TV if you have one.
Estimate hours/day of usage of each device and do the math. You might be
surprised.
Terry Tyler has a nice chart at the Tin Can Tourists site that spells
out usage vs. number of batteries and solar panels. You might want to
look at that.
FWIW: I can't imagine getting by on less than 80 AH of capacity unless I
was figuring on always having shore power and using the battery for only
alongside-the-road stops. You should investigate a good charger, as the
UniVolt isn't really meant for charging gelcells. It abuses conventional
lead-acid batteries, as far as that goes.
