Haven't heard them called 'dry cell' before... Optima batteries are AGM - Absorbed Glass Mat - they are sealed and non-spillable - but not dry or gell.
They differ from other AGM in their use of 'spiral cells' - versus flat plates.
I've used them - but not in RV yet... Be sure you get one with deep cycle capabilities - either yellow or blue toip - but must have light gray case.
And be sure your converter/charger can handle AGM batteries.
