winter cover help

Looking for recommendations for storage cover. leave Travel Trailer in seasonal site for the winter for last 4 years. Heavily wooded site. Decided to install a cover next year as it's getting too hard for me to get up on the roof and clean off all the leaves and debris and dirt. I find lots of broken tree branches every year and a mat of maple leaves. Would like to keep price around $200/300. 32' Keystone sprinter.
