effiecncy, doesn't change, 24v does not significantly increase efficency
what it does do, is 1/2 the Dc amps for the same watts load which means you can use smaller wire
that is one of the reasons 1200 watts is 10 amps at 120v 100amps at 12 means much bigger wire going to the inverter from the batteries
and why power transmission lines are HIGH voltage,
if your installing a Large inverter in the RV then 24v means smaller wire and less amps for the same amount of 'WATTS'
the fridge is NOT a big concern
base your design on how big an inverter you want, then decide on 12v or 24, lead acid, or Lithium
if you move around a lot the lessor weight of lithium is some advantage
if your stationary OFF grid, that advantage is lost, and the expense of lithium is many times the cost of lead acid, and AGM becomes a more cost EFFICIENT decision,
when buying lithium even a small 200AHr 24v system, aka 400aHr 12v is about $4000
, space/size is very close to AGM, the difference is the weight, NOT dimensions aka storage space used
