OK, here is the rest of the story. I purchased a 1.3 amp BatterMinder to keep the start batteries charged and the unit was defective. It drained my batteries so low over a three week period that they could not be recharged. I sent unit back for a replacement. The BatteryMinder gets great reviews and is sold by Camping World among others. I tested the defective one per the instructions given me by the contact person at BatteryMinder. Basically just hooking the unit up and testing with a digital voltmeter. That is when I noticed the battery voltage was slowing dropping with the unit plugged in. Same thing happened when I tested it on my car battery. Their instruction sheet clearly states that if the unit is attached without power , it will drain the battery(s). However, in my case the BatteryMinder was getting power from the coach which was on shore power. I know the shore power was on the entire time because my microwave clock was working in the coach and it goes into the blink mode when power is interrupted. Also checked the plug in for 110 with a voltmeter and it was good. Only previous problems with starting occurred when the coach was stored for more than three or four weeks without starting or charging. Even then, the cross over from the house batteries always started the coach. If the replacement unit doesn't work when I get it, then I will go back to square one.
