can anyone recommend a good rv cover. i've read some negative reviews about the tyvek and sunbrella covers lasting maybe one or two years at most. i live in the midwest and will only keep the cover on in the winter months.

Plenty of other toys to fill it!
I've used both of those brands and they are decent quality. I use my covers mostly to protect from sunlight and the UV damage. If you are only using in the winter then it should last longer than 2-3 years assuming you tie everything properly so it doesn't tear in the wind.
