Building a parking for the trailer and cover suggestions

We're going through the same thing now that our trailer repairs are getting close to being done. I'm leaning towards a stone base with maybe a carport type enclosure at some point. I may go with one on the tent type carports to get by cheaply for a while.

Earlier this summer I helped a friend put in a stone extension beside his driveway for his class C on is was pretty quick & cheap, put spreading a tri axle of stone isn't much fun.
