Thank you both , this is what I had in mind , take good photo of correct cable placement and even put it on the paper before actually doing any swapping.
Great tip on turning off as much as you can in the coach!! & isolating each cable ends.
I am thinking driving right to the store and also I can use the guys knowledge, that store has about every type of batteries thee , amazing!!!
Thanks again for the help!
