So you had ~230Ah capacity with two new fully charged healthy group 27s, and you need to know if 130 AH capacity is enough.
BUt we have no idea how much AH capacity you require, occassionally.
So nobody can answer your question without a bunch of supposition and guessing.
Sure we can - the OP has already qualified his reliance on battery power, saying it's restricted to the occasional overnight at WalMart, otherwise he's running on shore power. Although the OP never told us the make / model of batteries he has it's doubtful a pair of G27s would offer a 20 HR rate of 230 AH, more likely around 90 AH apiece. An Interstate G31 which he mentioned as a replacement would buy him a bit more at ~ 100 AH (20 AH rate). For his application that single Interstate G31 would serve his purposes just fine. FWIW, I run a single Interstate G27, even have a 1000 watt PSW inverter for those times we may lose campground shore power, and when I do eventually replace it I'll most likely do so with a single G31 which is totally sufficient for those of us who normally camp with shore power. :)
