Camping World doesn't "support" them. OCP is just another outside merchant who pays CW for the ability to have access to their customers.
Having spent almost 30 years in the Dallas area we've been to OCP, and heard their sales pitch several times. It is not for us.
However we know several local families who cannot take long trips, but make a lot of weekend trips with their kids to the area and regional OCP campgrounds. And love the convenience and amenities.
It works for some folks, and doesn't for others.
Personally we roam far outside the OCP area, so something like TT or Coast to Coast (owned by the same company as CW) would work better for us.
But being old farts, the U.S. govt Senoir Pass is our choice.
