Wanted: Spot to Park & Live in my 5th Wheel

We have purchased a 42' 5th Wheel and looking for a place to park & live in it all year round.  We would love to stay in the Kootenays. My one son goes to school in Rossland and my other son goes to school in Trail. Does anyone know if there is any place in the Trail area where we could park and live in our trailer all year round?  Thank you in advance.

Town: Trail, BC
