Stop the rain till I finish!
An alternative (since i live in the moonsoon too!) is to buy one of those 10' X 20' tents at Costco. It will run you about $150.00 and works real good. I have one over my boat and one over my trailer. Both my boat and trailer are longer than the tent, however most of them are covered. The tent needs to be roped down to the trailer. The tent comes with rope on all 4 corners. Also I have extended the height of the tent with PVC pipe.
Another added benefit is keeping the sun off of the unit too! One downside, my tent usually lasts about a year or two. After that the sun and wind usually take a toll and I replace the tent.
