I am going to have the batteries load tested. I have had the coach for almost a year now and never had this issue. Maybe you're right about the batteries or starter. Gonna check them out.
Save yourself some money and have the engine tested to verify it is turning over fast enough to build compression. If you load test the batteries and find they are a little weak you will buy batteries like I did but then end up with the same problem (maybe). If you start out and have someone test the RPM. Most diesel engines need to have a minimum rpm of 150 to build adequate compression to start. If the batteries are a little weak you can add jumper cables with the help of another vehicle to get adequate 12volt power. Even somewhat weaken batteries will turn over the starter but if the starter is dragging (and by dragging, I'm not talking about the normal sound of weak or dead batteries). I'm talking an RPM of 120 versus 150. I could not tell by ear my starter was dragging. If with jumper cables and help of additional 12 volt power it will not start hot you can rule out batteries.
