Understanding the chassis of your caravan can help you to know more about the potential problems that can occur. As the main skeletal foundation of your vehicle, keeping the chassis in top working order is important. A chassis is typically made of some basic pieces, including:
Despite being out of sight, you should always keep an eye on the chassis. This piece of the caravan provides vital support for the structure and acts as the foundation for all the weight above it. It also provides the main tow hitch, enabling you to pull the vehicle, as well as suspension mounting points.
There are some familiar phrases associated with the chassis of a caravan, and knowing these can give you a greater insight into the make up of the crucial structure. RHS (Rectangular Hollow Section) is a form of steel which is hollow and rectangular in shape. Sometimes known as cold formed rectangular hollow, this material is commonly used in the construction of the chassis. The process of hot-dipped galvanising occurs when iron, steel or aluminium is coated with a thin layer of zinc, creating a protective outer layer. DuraGal refers to a process where RHS steel is hot-dipped galvanised but the external zinc has a surface coating applied. This improves resistance to rusting and the adhesion of paint or other coatings. SupaGal is similar to DuraGal, however the RHS is coated on both the inside and outside of the steel. This makes it more expensive but prevents corrosion occurring from the inside.
No matter what your chassis is made of, it is important to keep an eye on it. AL-KO, a large manufacturer or chassis, recommend that these are washed using a pressure washer annually to help prevent the build-up of salt and dirt.
