follow me and I will make you fishers of men.


One of the bigger standard deep cycles. The 24's just do not seem to run
that long. My camper came with a grp 24 and would not go a night if any
heater blower use. Changed to a Group 31 and runs fine now. You may have a
problem with the battery tray fitting a group 21.
