You seem to be taking the right steps. I hope your budget includes more than one employee. You are going to need staff to run the office, clean the restrooms and the rest of the facility and provide security. It is our experience that problems always arise at the most inopportune time. Power or the internet going off in the evening isn't going to wait until morning. A plumbing leak or sewer stoppage is a problem immediately and a disaster if left unrepaired over the weekend. Since you imply you have somewhat limited RVing experience, I would further suggest you and your wife consider workamping for a few months. That would give you much insight and personal experience as to what can and will happen on a typical day. Learning it might not be the right business for you is a lot easier to stomach after a few months of working for someone else than it is to learn it after investing a million or more dollars. We have worked with five prospective park owners over the years and the results were very much mixed. Three went on to own parks and two decided it wasn't for them. Though I believe all five left with different ideas of what ownership is like, both positive and negative.
