12 volt issue
I have a 2013 Coachmen on a 2012 Chevy 4500 chassis. I am having a reoccurring issue with the ‘run/crank’ relay. When it goes out starter solenoid will not engage. Fuse box, on my unit, is located under the hood drivers side under the brake master cylinder.
The AC relay next to it is the same relay (part number) on my unit. Swapping them is how the mechanic confirmed it was that relay keeping it from cranking. Went to parts store, bought two so I had a spare. Went out again months later and so I now carry two.
This may help you find another possible repair area to consider.
