I did that mod to my 95 Bounder.
You will get tired of listening to that mechanical contactor going clunk clunk clunk clunk.
I elected to use Solid state relays in the AC. I have complete control of all functions from the thermostat.
Fortunately my RV had 6 small control circuit leads from the AC to the circuit breaker panel. Didn't have to run wires through the ceiling.
If you elect to try the solid state relays. Spend the extras $$ for a 50 amp relay or better for the compressor. The back EMF imposed on a smaller relay, when turning off, will make it fail.
