The one I bought worked perfect. I was not aware the connections would be different. The only thing you should be aware of is the width between the hot and cold water valves.
The one I purchased was a 4", where the other size which is much like our faucets in the house is an 8" faucet.
HAPPY CAMPING!! :D
