My advice would be to find a park that is affordable to you without work camping. Then work in that park for the enjoyment of working there and to earn some spending money.
I know four people who were doing what you would like to do. Two were 'let go' from their jobs. One was able to sell his park model and move to another location. One just stayed in her park model and found a job in another park. Two (married couple) developed health problems and couldn't work any longer. They tried to sell their park model, but could not find a buyer. They just finished filing bankruptcy. They are stressed that they are not able to afford the rent without the work camping jobs.
So, find a park model that works for you and consider work a 'bonus'. If the job does not work out, you will not be dependent on it to help pay your rent.
