I have to replace my coach batteries. Presently, I have two Interstate 31-MHD CCA 950 batteries installed. Where I am located, it would be convenient to replace the two Interstates with two Durala...

Can you tell us again whether you are replacing the chassis batteries or the house batteries?
Chassis batteries are for starting the engine, usually rated in Cold Cranking Amps. Gassers generally have ONE 12 volt chassis battery.
(DP's often have 2)
House batteries run the house, and configuration can vary all over the place. These are generally deep cycle batteries, and they are rated in ampere hours based on a 20 amp draw. As an example, the common CR2 size 6 volts are rated at 220 ampere hours or more.
Many gas coaches will have a pair of 12 volt house batteries, often Group 31's where many DP's will have 4 CR2's.
If these are your house batteries, you want the highest amp/hr rated deep cycles you can afford.
