This is our second season using this cover on our Sprinter camper and it still looks as good as new. Keeps the rain, bird droppings and tree sap off. Good breathability too - no condensation issues at all.
Does everything we need at a reasonable price. Our Ducato-based campervan is well protected through the winter months. The triple layer fabric is a good balance between protection and weight. Easy enough to fit on your own once you get the hang of it.
