Talleyho. If one cannot afford say $900 for 15 meters then they should forget about starting an RV park. In the USA a new RV park would cost about $5000 to $10000 per site. Even in Mexico there are lots of costs. How about $5000 or more just for a transformer from the CFE. If the park is not near some heavy wires there is another cost to bring the lines to the park. You need a large septic system. Underground copper wiring. Power pedestals.Levelling of the land. Maybe gravel. Washroom.Small office. Then you have to tackle the bureaucracy that will put sticks in your wheels. Zoning,permits and lots of mordida! Why worry about a few meters.
