Coach Battery Replacement Help

I just replaced the batteries in our unit. After much checking of proces I determined that O'Riellys had the best prices and warrenty. In our case the Starting battery is a regular 12 battery and the Deep Cycle batteries are 6 volt golf cart batteries. Our original batteries were interstate batteries and they changed the batteries a bit. I found the Interstate to be about a 1/2 inch longer and an inch and a half taller than the originals. The O'Rielles replacemnts were 1/4 inch bigger on the foot print and fit very tightly and were about 1 and 1/2 inch taller than the original which made for a difficult pacement but it worked.
