Yes, the kilometers can give you a good idea of how much the campervan has been used. However, don't let a high kilometer number put you off completely. If it has been well looked after over the years and it's a good brand, it is more than likely still good to go! Just like an old land cruiser, if they are well maintained, they will last a lifetime! So don’t stress if the km’s are high, focus on how it has been looked after.
