Do caravan covers cause dampness?

In this blog post, we will answer the following question: Do caravan covers cause dampness? We will discuss the pros and cons of using a caravan cover. We will also explain the importance of investing in a good quality caravan cover and advise you on what type of caravan cover is the best. 

Do caravan covers cause dampness?

Cheap, low quality and hard plastic caravan covers can cause dampness. Plastic caravan covers allow water to gather on top of the caravan, making the vehicle “sweat”. This can cause dampness issues inside the vehicle, affecting mainly the roof. 

We recommend you invest in good quality and breathable caravan cover. If you do not use a breathable cover, it may happen that your camping equipment absorbs moisture causing mould and/or corrosion, which is detrimental to the quality of your caravan. 

There are many brands that offer very good quality motorhome covers and tarps. Here are a few:

  • Fiamma motorhome covers
  • HB Collection motorhome covers
  • Hindermann motorhome tarpaulins
  • Tyvek covers
  • HTD motorhome covers.

Why invest in a good quality caravan cover?

Rain, snow, dust and sun rays, in addition to acting directly on the body paint, also damage the lights, the rubber of the windows and the doors of the caravan. Not to mention that the stickers on the vehicle fade, leaving behind the memories they represent. Therefore, buying a special cover that protects our caravan seems like a good idea.

Campers have some controversy regarding this item. Some claim that it is not necessary and others claim that instead of protecting, it only helps deterioration to take place faster, by retaining moisture.

To control the inconvenience of humidity, it is necessary that the cover is breathable. In this way the water that condenses inside the caravan can escape to the outside. In turn, the covers must be waterproof so that they do not allow water to enter.

Caravan covers are a good idea even if the vehicle is not outside in the elements. In the garage, dust and moisture can also get in and wreak havoc.

What caravan cover to buy?

If you decide to buy a caravan cover, you should know that although size is very important, it is not really everything. In addition to the size of the cover, you have to pay attention to other aspects.

Size: First you have to measure the length of the caravan, including the gas tank and any protruding elements. You must bear in mind that a cover that is too large will be a problem if the caravan is located outdoors, as it will be difficult to adjust it and the wind could end up tearing the fabric and breaking the straps.

In addition, if the canvas is not properly adjusted to the caravan, moisture will easily penetrate and can damage the exterior elements of the vehicle. Another important aspect is that when the canvas is loose, the wind will cause it to rub against the surface over and over again, which could end up damaging the exterior coating of the caravan.

UV resistance and impermeability: In these aspects, special emphasis must be placed, since water and sun rapidly deteriorate the materials of caravans that spend a long time outdoors.

The covers for caravans must guarantee protection, even in winter times when the rains or snow are constant. If they are not waterproof, the water will reach the surface of the caravan and cause damage sooner or later.

Also, when the material of the cover is not resistant to UV rays, not only will the caravan be damaged by the direct action of the sun, but also because the cover itself will deteriorate rapidly.

Breathability: When the material of the cover does not allow accumulated moisture to evaporate, it can cause unforeseen damage such as oxidation of the exterior coatings of the caravan. This results in mould stains that can even get inside the caravan and settle on the upholstery. Window and door rubbers may also deteriorate.
