Your main issues will be electric service, and maybe water.
RV spots are usually 30 or 50 amp service, and that (new) mobile homes are 200 amp. Depending on how your electric is setup in the park this could be a fairly straight forward exercise, such as if you have overhead service everywhere. But if completely underground it might be an undertaking to get larger wire run to the pads.
Water service is sometimes 1/2 inch spigots with RV’s, which need to be upgraded to 3/4…could be a non issue. Sewer connections are typically not much of an issue just a routing exercise under the mobile home.
I assume your city has no issue, which could be another challenge depending on the conformance of your property to zoning. Do your homework, and get lots of estimates as it will help identify gaps or nuances you didn’t think about.
