Here where we are seasonals for the summer (MI) the park mows, usually once per week and trims every 2 or 3 weeks, but, they do not like to get too close to any of the campers things. So, many have their own electric trimmer to get areas the park doesn't, or spiff it up if they have someone coming, small blowers for blowing leaves off their patio rugs or decks. We did see several parks when looking that required a seasonal camper to mow their own lot.
