MH wont start on chassis battery. Has 13V
I have a 2008 Country Coach Affinity. It will not start (not even try to crank) on the chassis battery. Everything lights up on the dash OK, it even shows 13V on the voltmeter. Turn the key and not...

Wondering if you connected all cables when you replaced the batteries?
BIG HINT: Always mark all cables and take pictures before you start. A club members friend replaced his batteries and the rig would not start. He was in total denial that they weren't connected correctly. After he finally calmed down and let me look I found a unconnected cable.
The combiner or boost is a solenoid that connects the 2 battery banks. It should be reasonably close to both battery banks.
OP Your unloaded voltage readings don't mean much. Connect your voltmeter to a good FRAME ground. Then when trying to start measure to the negative battery post (should be almost 0V) then the positive battery post (should be 12V+). Continue towards the starter until you find the problem.
New batteries fail - have them load tested.
