Can a landlord serve a 3 day notice within a week of already serving a 30 day notice?

We are in an RV park and they told us that we were trying to sneak an RV in but it is the original one on our paper work. A couple of months ago, we started buying a trailer off the park so the original one was just parked. We took it camping for a weekend and pulled it next to our new trailer to clean it out and plugged in the power to use the vacuum. Then they said that we need to pay for another spot and were causing us of sneaking it in the park. They even tried towing it and lied to the tow truck driver. They said that it was abandoned. He saw us and talked to us and realized that it wasn't and left so then they serve us a 30 day notice about a week ago. Today, we got a 3 day notice to pay or quit but they still have our deposits for $400 and rent is $450.
