Charging a pair of USB2000 golf carts with the Rogue MPPT 3048. US battery says the absorb voltage should be 14.7V (for 2 GC2 in series) held for 2-3 hrs, with charge terminated by max time or when...

Either this, or leave it slightly below the recommended 1%C. When you are "camping", rather than just "charging", there is always some load even when you've turned off everything you could. Fridge, LP sensor, and self-discharge alone can draw 0.8-1.5A. So if you set FLOTR to 0.5A, it will never drop that low, and then timer function FLOTM will run 2 hours just like you wanted.
This controller has probably more adjustable parameters than any other MPPT, and they are easy to play with because of built-in interface.
The ultimate choice will depend on the SG results. I can't measure it in my AGM, so I'm relying on battery specs and rested voltage in the morning. But you can.
