Don't know much about toy haulers, so this is new to me.
Initially, I thought you meant circuit breakers, but they don't cost 300.00 each (the entire power center can be replaced for under 200. (8900 Series Electronic RV Converter Center, 65 Amps - $184.95
So, someone help me. What went wrong; where are the 3 relays; and why did it cost 900 dollars to repair/replace them?
If everything was OK until you turned on the air, you might have overloaded the campground's supply (if it was only 20 amps), or if there was a problem with the air, you should have blown two circuit breakers at most (main and air conditioner) and they don't get replaced; just reset.
If you have a 50 amp service camper plugged into a 50 amp supply and there was an open neutral (such that your camper was supplied with 220 VAC across the power center instead of 2 110 circuits, way more than the power center should have blown (like the air conditioner, microwave, etc).
In any case, it would be another case for a hard wired (or dangling) surge supressor.
