No Power to Dash/Chassis
So I go out to crank my motorhome. Batteries are fine. House power is fine. Everything works on the house side. But I have no voltage to the power distribution box located under the driver area. ...

I tried to find one that looks like this that is considered "continuous duty" but failed. I have to assssssume the one pictured is a starter motor use relay. Maybe 1.2 ohms resistance across the magnetic coil.
If this rig is a pusher diesel with larger than a seven liter diesel engine, it would require an expensive relay like this to power the jump start which can range to 500+ amps and even more than that in cold weather.
This is an image of a 200-amp bi-directional SMART relay which would pass the power of all but the largest alternators.
With a 7.0+ liter diesel engine I would not elect to use the "feature" of this smart relay to jump start from bank to bank. I would retain the relay what is featured in this thread. Two relays each best suited for it's purpose.
By selecting the BI-Directional model relay the relay will operate and pass current no matter which direction the power is coming from -- alternator or converter. This keeps chassis and hotel batteries happy.
