Metal storage structure for 20 foot long travel trailer?

We purchased our canopy at a dealer in Vancouver. It was manufactured back east and distributed out of Salem. I believe the name was Western Steel Structures or something like that. Their work was good as is the product, and I thought the price was fair.

I bought a standard 14' x 36' canopy with 12' side walls. Due to the roof pitch, it has no problem accepting my 13'-1" fifth wheel. My trailer is 32' so the ends get wet in the northwest weather. Roof is dry and shaded all the time.
