"an air gap in the water heater tank"? I've never done it and never heard of it before, I would think that when pressure builds up and is not relieved from using the hot water then the pressure relief valve would bleed off the excess. It's not done in residential heaters why risk overheating your RV heater because of not enough water?

Actually the air void is more or less the top 1.5 inches of the tank. Unless you live in your trailer full time the air pocket is automatically maintained every time you drain your system for storage and then refill the tank. There is no required special method to fill the tank.
As for home systems many have thermal expansion tanks and vertical dead legs to take up pressure fluctuations and minimize hammering. Many of the tanks themselves also have a built in void in the top of the tank that again requires no special procedure to maintain the air pocket.
