I replaced the Interstate group 24 that came with my fall purchased camper with 2 new 12v Trojan 1275's that I got from the dealer that I bought my golf cart from. It used 4 (48v system) and I had him bring two additional new ones when he delivered the cart. I barely got them on the front of the trailers battery tray once they were in battery boxes but they did squeeze in after removing one of the tops extension that allowed the battery cables to be routed from the side.
Looking forward to seeing how long they will let me boondock without the genny recharging them this Summer and Fall. Not expecting miracles but their a nice battery.
Don't forget to follow these instructions (eg, 14.8v and sometimes 16.2v) or your batteries won't last. Hope you can get at them both with an hydrometer too, or else you won't be able to tell what is happening.

No idea what sort of recharger your golf car has for its Trojans, but your RV converter will be unsat--unable to meet the Trojan's charging spec vopltages.
I like this unit for that job, don't know of any others with the adjustable voltage. (don't forget to adjust the 14.8 up in the cold and down in hot temps--14.8 is for 77F.

The 60 amper there will run on a 2000w gen but the 75 amper will need more of a gen such as the Honda 2200 (if they have fixed those) the two T-1275s at 300AH can handle a 100 amp charger but that would need a 3000w gen to run it.
