If you camp away from power, even for only a night, I highly recommend two 6V golf cart batteries. The hold much more power than any one 12V battery and are not that expensive.
The OP already said - " I wont be going off the grid with it", in which case a single garden variety Group 24 12 volt flooded marine / RV battery he can buy anywhere would serve his purposes just fine, no need for him to spend any more $$$ even if you would. :R
I'm going to go with the oldwizard1 on this. I believe two GC2 6V's are an upgrade to a single hybrid 12V.
Yes, the single 12V will most likely serve as a decent power source for emergency braking, using a hitch, slides, and limited lighting. Thereafter, to be connected to shore power or recharged by generator.
However, there may be times for more 12V use or insufficient charging takes place. The pair of 6V's will offer more reserve and are much more durable than a hybrid 12V. I think some of that transfers to $$ efficiency and ROI of battery power.
The OP should also be informed not to store his new RV with the battery connected. Some install a disconnect switch or remove a battery cable. If not, the parasitic draws of the circuit boards and alarms will draw down the battery to "dead", within about a week (depends on RV's devices and size of battery, temperatures).
