hi bb i purchased a cover from camping world in burlington washington. about an hours drive from where you live. costs any where from 250.00 and up. quality costs. had mine for about 5 years and is still good. unfortunately my trailer was stolen so will not be able to use until replaced. i had a 19 footer. my next trailer will be my third escape. my first was the fourth 17 footer rease made in the " barn ". my next trailer will be the 21 footer. since these cover will fit larger sizes than say the 19 footer it may fit my next 21 footer. if not i could make a deal with you at a very reasonable price. if interested 604 535 9809 tom
We use an Elite which we purchased from ebay. It does a great job. It includes air vents, so we've never had any mold issues. I recommend the model containing side zippers so you can access your trailer interior without removing the cover. They run about $140-$150.
