Voltage vs SOC is what you have to worry about. Two batteries can be at the exact same voltage and have different SOC and capacities (especially LiFePo4). A charger that switches between constant voltage and constant current can cause issues with different batteries. It's not all about voltage.

@BruceMastiff
You need to jump in on here….
First question - why wouldn’t you just use the battery tender?
2nd - will you have a shore power hook up to use the battery tender as well as keep the RV battery topped off?
3rd - if no shore power why not remove the batteries and take them inside and put them in storage (or use battery tenders).
Lots of unknowns here while people debate on what you propose.
My opinion is that it is not a good idea to charge anything but identical batteries on one charger. Sure, you can, but should you? - probably not.Larry KE4DMG

Thanks everyone. I would have participated sooner, but I wasn't notified this place was still active.
I do fulltime with constant 30A. I was plugging my tender into the same outlet as my Progressive Dynamics converter. My RV battery compartment right next to my Rhino 660 (motorcycle battery) and old VW. The house battery is being "charged" constantly and just had an idea of splitting that 12V to my car and Rhino. I posed the question here because I am NOT an electronic genius and assumed "12V isn't just 12V". All the batteries are "good". I was just thinking I could skip an outlet and a second charing device and just let the converter just do what it does, and knock out three items at once.
Thanks for all the input guys, but since the OP got two very quick and direct replies, I just got a splitter for my battery tender for the car and rhino only. I am still curious where this goes though.

My original idea was to install a wall mount like this from my house battery and run two 12' extensions to each of my vehicles. Less mess, wires, and an open outlet plug.
