I set up an RV park in 2020 and in 2021 I had a contractor build a $45,000 open Pavilion on the property. Where do I add those expenses? Do I add the pavilion to my assets as well for the property?

Most likely a business asset, but you will have to determine the recovery period depending upon the nature of the "Pavilion".
