Having inverter issues. (Long post)
When I bought this coach it had an inverter that was not also a transfer switch (separate charger and inverter) so there was one transfer switch that controlled the switching between shore power and g...

While I don't see a problem with how you wired the input (parallel wires) other than it's a safety hazard why not rewire this correctly? Namely a dual 30A CB and a 4 wire 10ga romex from the panel to the unit. I would not connect it up to the ATS w/o CBs.
The unit is not a 50A pass through, instead it's a 30A unit that can accept 120/240V input. It does not appear to have 120/240V output but instead it has 2 separate 120V outputs since the outputs are labeled N1 L1 and N2 L2.
Bill, I would do the following:
1. Rewire the input to a 4 wire dual CB for safety and that will eliminate the business of parallel input wires.
2. Disconnect the output wires and remove all loads from the circuits. Ohm out each circuit and you should have no continuity between the ground/neutral and ground/hot. Then check frame ground to all 3 wires and again there should be no continuity. I'd also check neutral/hot to help verify that nothing is connected to the circuit. You're checking for bonding on the circuit and there should be none. The unit bonds neutral/ground when inverting and not otherwise which is correct and there should be NO bonding on the circuit between ground/neutral or frame ground/ground when the circuit wires are disconnected.
3. Connect one of the circuits and see if you still have the problem. Then repeat for the other circuit.
4. If you continue to have problems run temp circuits from each output and add loads. This should not fail and would point to a circuit related problem.
