I just completed this mod today. Thanks to Chester for the pictures and Richard for the dummy resistant theory of installation of the mod. I also made sure the upper and lower circuits on each side did not use the same hot leg so the loads will be more balanced.
I was able to source contactors locally for $22 each. MCG Industrial PN: MDP30A-2P-120

These contactors have two circuits but I only used one side of the contactor. They also need a pretty tall enclosure vs. the short box I saw on Richard's coach. It is more expensive and water proof but the supply house had it on the shelf and I was able to mock up the inside of the box while in the store.

The first side took me about 3 hours to complete. I took my time and checked things 3 times over before I snipped any wires.
The second time (1 week apart as I was awaiting parts) took me 2 hours to complete. Again I was working slow and methodical. The penalty for screwing up far exceeded the reward for finishing an hour early.

Thanks again to Chester, Richard and all those who added to this thread. Each entry was important to help me understand this.
