Multimeter did not read anything.
RV has been in storage... unplugged sitting in driveway, battery switch on (DAH)
I found the problem..... I left a storage compartment light on.
Batteries were charging for several hours and my test meter kept reading low, then I realized after I posted, battery tester is for 12v batteries not 6v batteries.
This could go down in history as one of the dumbest things I have every done, however, my life is not over and I am sure I will do something dumb in the future, so time will only tell.
Thank you all for your assistance.
