When purchasing a used caravan to enjoy travels around the country in, one of the most important checks that you must perform (after looking for damp, of course) is for rust damage.
Rust is what occurs when iron and other metals begin to naturally breakdown as a result of exposure to the elements.
Not only is rust entirely unattractive, it can cause all sorts of problems in a caravan.
It is important that you ask the right sorts of questions when viewing a used caravan to determine whether or not it is likely to have been subjected to some sort of rust damage.
Ask the owner what sorts of areas they have travelled in and at what times of year, as snow and salt can make the van more prone to rust; ask them how the caravan was stored, as being indoors can lessen the risk.
You cannot simply take the owner's word for it, however, as the less reputable sellers will not be above lying about the condition of the caravan in order to ensure a quick sale.
Instead, you should thoroughly check over the van yourself, looking for signs of orange-y rust, especially in the frame.
These vans should be avoided at all costs, as there is no fixing structural rust.
Whilst a little rust on the steps or windows of a used caravan is not all that bad (you might be able to prevent further damage from being caused and reverse that which has already occurred), vans that feature large patches or damage in areas integral to its operation should be avoided at all costs.
The last thing you want is your caravan to fall apart as you tow it down the street.
