This particular subdivision would only allow a motorhome or trailer for up to 18 months once you have received a building permit. That is the common practice for most subdivisions.
There are many other parcels available in the area that do not have such restrictions and would allow you to keep and or live in a motorhome as long as you meet the environmental health codes.
Please feel free to give me a call if yo have any additional question.
