It is always important to protect your caravan or RV from damage, which is why most sensible owners make sure they use a proper cover. However, not all covers are created equal, so you'll want to think long and hard about the different kinds available, and one of the most important decisions you'll need to make is whether to go for a canvas cover or one made from PVC.
Though PVC covers do have their advantages, it is nevertheless the case that canvas covers are usually more advantageous, and here are just a few reasons why.
People are often misled by the fact that PVC covers will theoretically last longer than canvas covers; however, this is only if the PVC cover is never really exposed. One of the biggest problems that comes along with using a PVC cover is that, though they are quite strong, they can be cut through very easily. Imagine taking a knife to a PVC cover versus a canvas cover; with its denser fibres and tougher structure, canvas has a distinct edge.
Of course, it's very unlikely that anyone is going to take a knife to your trailer cover. But you do need to think about bumps and knocks that can occur accidentally. Additionally, birds and small animals will more easily penetrate a PVC cover with their claws or teeth.
Seams vs seamless
Compounding the strength issues that come with PVC is the fact that PVC often leaks or develops tears where it has been sewn up. Because PVC is a completely solid material, holes need to be punched through in order to join pieces together, which is obviously going to have an impact on the structural integrity of the material. With canvas, structural integrity is not an issue. Holes do not need to be created because canvas is woven.
PVC is completely waterproof. That might seem like a point in PVC's favour, but this is not the case. The issue is that PVC tends to trap moisture that condenses underneath it. When that happens, the fact that PVC isn't at all breathable means that moisture isn't able to get out either. Instead, it will just sit there against your RV or caravan. Unfortunately, this can often lead to mildew and mould. In contrast, canvas is able to block water from penetrating, and its breathability will mean that moisture doesn't become trapped.
