2003 Itasca DP does not always start

[SNOPRO711X]

Last week I got the oil changed on my motor home. On the way home I stopped for fuel. When I tried to start the rig nothing happened when I turned the key. The next time I tried to start the rig it fired right up. It started just fine after that until today. Today it acted up again. About half the time nothing would happen when you turned the key. I checked the voltage at the battery and got 12.59 volts. That seems a little low to me. The batteries are not quite 3 years old.

When it does not start it does not even try to turn over

Any ideas.

At one time I owned a 2003 Winnebago DP. As I recall, some owners had an issue with the ignition switch. Also, there are 2 or 3 relays mounted on the chassis near the starter that have had issues as well.
