Based on a positive comment here on the forums somewhere, I investigated and purchased this Wolf Tyvek Trailer Cover from www.Covercraft.com .
This is, of course, a stock cover made for trailers 22 to 24 feet in length. I thought it was a pretty good fit overall. I removed the tri-tank cover since the trailer cover just wanted to slide back up the nose at that point.
Installation went about as well as I expected - awful. Once I enlisted a second pair of hands it went a lot better. This is not a job one wants to do every weekend.
The material is much heavier than I expected. I thought "Tyvek", ok, that stuff we staple to house sheeting. It is not like that at all.
So far so good.
