Group 29 VS Group 27
Installed group 29 batteries to replace the original group 27 that came with the RV. Besides the size and capacity is there any problem with going to a higher capacity battery than came originally?

That's kind of what I'm getting at.. so many trips are fairly short. I've seen people dry camp for three days at beach and drive 40 miles home. Then proclaim their batteries are charged and park the RV for a month in a storage lot.
Don't fall into that trap. When the RV is tucked into storage, have some kind of system to monitor and keep batteries fully charged. It will be money well spent.
Also-I've noted house battery voltages (not charge current). I've seen mid 14s when initially starting cold engine, but once underhood temps get normal, I've seen 13.6-13.8 volts on house batteries. To me that is occurring at a place in charge cycle where the batteries should have the full on 14.4 volts. I do not see alternator output optimized for charging two deep cycle batteries ten feet away from the engine compartment.
