Oh boy where to begin. Yes I own a campground that I built 20 years ago. It was an instant success after 10 years. Fortunately I needed the right off and now that it is making some money I can use the income. It has not been one of my better projects but there is a long term objective.
You do not say what part of Texas so is it a Snowbird area or a summer time area? Being in the mountains where it's too cold in the winter, we are close for four months. I started out with a combination of seasonal and overnight sites but my short term sites were rarely over 30% occupancy. Several years ago I went to seasonal only partly because there is a Walmart a mile away. Yes, I stay at Walmarts when traveling.
Being closed for several months has some real advantages in that it keeps people from living on the cheap in your park. The phone rings: "How much is it to stay in your park a month?" You know we are closed in the winter and that you pay in advance for the eight months of use and four months of storage? CLICK
Fortunately I had a couple that managed the park for most of the years. He was a farmboy that never learn there was only eight hours in a work day and he was very handy. She was good with people as I probably would've run many of them off. There is a lot more to running a campground and most people think, especially with rigs coming and going at all hours of the day and night and forgetting to unhook from the water and power.
Like Hunt public storage I look at the campground as a temporary use of lake front property that will become very valuable in the future as a 80 unit condominium project. Not in my lifetime, but some day.
Hope this helps.
