I hav eused both Trojan and Sam's golf cart battery in a high draw down marine application. Both seem to be very good but I would give the edge to the Trojans. However, last time I checked the 6V Sam's battery was about 69.95 . about double that for the Trojans. Not sure I could justify the difference.

Another Battery to consider is the Rolls. Strictly commercial and very Heavy Duty. Priced accordingly.
