It sounds like you're not sure what kind of Park you want to operate. Once you nail that down you can define the actions to get there.
I personally don't want to deal with weekly rentals and collections, regardless if they're long term tenants. I want lot rent only, no mobile home repairs, and world peace. Not everyone wants these things, so need to understand what you want to help with recommendations.
Hopefully you didn't get a loan against the value of the weekly rental home income as that will limit your options.
