Ok, if always plugged in to reliable power.. A group 24 MARINE/Deep cycle will handle the brakes should the cable (Break-a-way) get pulled.
But for "Off grid" (not plugged in) camping you need AMP hours, and that Group 24 has beasally.. None (About 25 you can use)
the GC-2 Golf Car battery, this is a six volt so you need two of them in series provides 210-230 amp hours total capacity, you can use half (over 100 AH) safely. it is about the same "Footprint" as a group 24 but somewhat taller so make sure it fits before you spend. This is the best BANG for your buck if you get flooded wet cells at Sams or for a few more bucks at Costco.. (I do like Costco more than sams for political reasons I won't go into)
Now there are other types. AGM for example.. but lots more money and not much difference in the "Bang" (Amp hours) dept.. AGM are, however very low mainentince where as Flooded Wet's you have to check and water (DISTILLED ONLY) from time to time and clean more often.
