Since you no longer dry camp it should work just fine
The big advantage to the pair of 6V=GC-2 is capacity (220 AH give or take and half usable) this compares to one 12 at
Group 24 75 ah
Groups 27/29 just under/over 100 AH
Group 31 about 130 ah And only about 1/4th usable.
So that's the only major difference.
Not relevant to the OP as he doesn't need a lot of amp-hr.
But 6V Golf Cart batteries are true deep cycle batteries and will hold up much better to regular discharges down to 50%.
Other than a few hard to find specialty batteries, pretty much anything you find in 12V is really a starting battery that won't hold up as well with deeper discharges.
They are constructed differently with deep cycle having fewer but thicker plates, so while they won't put out as many amps, they can do so for longer and can handle it without damage.
But again, if the OP isn't going to boondock, he needs enough to run the slides out which in terms of amp-hrs is nothing when you will immediately either plug into shore power or start the motor and recharge them.
