Battery Tenders
I have two new RV Batteries and want to keep them completely charged. Stupid question I know, but here goes. What size battery tender do I need to get and can I just hook it to one of the batteries in...

Three things you should have with your new batteries: A disconnect switch so that when in storage you are not powering any alarms or other parasitic draws, a meter to accurately monitor voltage in the 12V system, and a hydrometer to see what is happening, chemically, inside the batteries. The electrolyte should be checked with the hydrometer during the first 10 or so charge cycles to arrive at a base line Specific Gravity. That measurement will be referenced for the life of your batteries.
If you are one of those that doesn't have time to do the steps to insure correct battery health ("they should be OK...."), no harm, no foul. You will just be buying new batteries sooner rather than later.
BTW, the WFCO chargers (various models) are known to have problems with correct staging/output and may lead to early battery demise. I'd suggest you shop for another converter to be used concurrently with your 12V system. You can pull the WFCO, let it remain but unpowered, or use it too.
FWIW, I have a Progressive Dynamics converter that is 45 yrs. old and works perfectly. I guess nothing more needs to be said.
