I would warn you guys about taking your coach to Sam's to have the batteries replace. A friend stopped at Sam's on the way to AZ. to change his batteries because they were shot. The guy at Sam's changed them out, but the coach only lasted 150 ft. and quit. He got out to see what was going on and the whole engine compartment was on fire. He ran back got his fire extinguisher and got the fire out. Long story short, it totaled the coach. Sam's tried to buy him off, and fix the coach, but what they offered was nearly an insult, so he called his insurance company, and they totaled it. Told him they would get the money back from Sam's. So be forewarned, before you sail into changing your batteries, take a picture, smartest easiest way to be sure you have them right.
I have been looking at batteries to, I have Duracell's in my coach, I have one that's FUBARED, but I think it will get me home. The battery that are in my coach are $108.00 apiece.
