I'm not familiar with your coach, but if you have two air conditioners you probably have 50 amp service. Google 30A RV connector and 50A RV connector to get pictures you can compare to your power cord.
The amp rating of a service only tells you what it can supply. 50 amp service is like two 25 amp services, it uses two hot wires and a neutral, along with a ground, thus a 4-pin connector, but it is NOT like 4-wire receptacles in your home. They have 220V from hot line to hot line, RV service does not. Hooking your RV up to a home style 220V outlet may damage RV components. 30 amp service is one hot wire, neutral and ground on a 3-pin connector. Most campgrounds with 50 amp service also have a 30 amp connector, but some don't. It is a good idea to carry a set of adapters anyway. A 50 male to 30 female lets you plug your 30 amp plug into a 50 amp outlet. A 15 male to 30 Female lets you plug into a 15 Amp (Standard home outlet) to keep batteries charged, run the fridge, etc. but will not power an air conditioner. It might power a microwave, depending on the wattage. The reverse, a 15A female to 30A male is also handy to have for testing power.
It is also a good idea to carry a tester. I use a 15A outlet tester available at most hardware and home improvement stores. I plug it into a 15A female to 30A male adapter so I can plug it into whatever 30A outlet I'm going to plug my trailer into.
Some get a combination tester/surge suppressor. I don't have one yet but am considering it. They are more expensive, in the $150 and up range.
