Please recommend a good cover for 5th wheel

[vipermanden]

My new Montana 3820FK with full body paint will be arriving in the next few weeks or so, and I want to get a really good soft cover to protect the paint job, since there are no covered places to store the 5th wheel that have available spaces near North Lake Tahoe. I was told I should get one that is really soft on the inside, and that will last 5+ years on the outside. What cover would provide this type of protection from sun and snow etc.

Thanks in advance.
