Thanks, Randy. What battery(ies) do you have in the RV? I only have a single 12v RoadHawk Predator RV which CW put in when we purchased. It is a DC27 with 575CCA and 705 MCA with 23 Amp Ave. I think it is a Deca battery but can't find any details on it such as AH rating, etc. My assumption is that it is the cheapest battery available since CW put it in there when purchased. I think the original battery box can hold 2 group 27 batteries or at least 2 group 24's. I was thinking of getting 2 from Batteries Plus. The have Duracell group 27 batteries with 90 AH for $110/ea. I don't want to spend several hundred dollars replacing battery box, wiring, etc. for something that we only use 3-4 hours per day while driving. Does this sound sufficient?
