It is not cheap to remove these items for inspection but it is the only way to do the job correctly.
It's well into August, the motor home is coming out for football. Sounds like it's major purpose is tail gating. So instead of disassembling the brake system piece by piece to "inspect" it why not use some common sense and ask a few questions about usage?
If it gets a few hundred miles over a couple of months a year a real good place to start is sticking calipers, not linkages which very seldom fail, are never lubed, and protected inside the vehicle.
Almost always under such circumstances calipers stick because of corrosion. You can confirm or eliminate a whole bunch of what you want to tear apart by checking how many hubs are hot, common sense is a big part of repair. Check the OBVIOUS, repair what is necessary, check the operation, and move on.
