We have decided to try and get the Mercedes registered as camper instead of work van. We can then carry passengers in the rear of the vehicle.
The plan also involves a third bed for Em and a movable toilet (more on that later) as well as the ability to carry full sized sheets of plywood (122 x 244 cm.), Laser masts, booms and sails and finished kitchen cupboards.
Not an easy design brief but the first step has been taken this morning when we bought this bench seat. Fits as if it was made for the job. Back to work.
