On my 30AMP MH I added a 35AMP box that uses a 30AMP cord to the shore box. The OEM 30AMP cord I use a adapter for the 50AMP shore box.
I placed the box in the compartment right under the OEM breaker box. Then ran a wire up to the breaker box and put a female end on it and put a female end on the AC breaker box wire. I put a male end on the wire that goes to the front AC. Now I can use the outside 30AMP or the inside when wanting to use the generator.
I put mine on the front AC because it is a 15K heat pump and bedroom AC is a 13.5K cool only. In breaker box to front AC is a 20AMP breaker and a 15AMP for outside use.
