1600kg is not a lot of tow capacity - only 3500 lbs. A base model Mustang for instance comes in at 3600 lbs. Most campers are going to exceed it as well especially when you add in supplies, etc. And that is not using a trailer.

Most people also do not realize - you need to count the weight of the trailer, hitch, cargo and passengers against the rated tow capacity of the vehicle.
