This caravan measures just 14 studs long (excluding towbar) and 8 studs wide yet is packed with lots of detail.
About this creation
The window at the front is a ship's window fitted upside-down using hinge plates with one side inverted. The wheel on the towbar folds up when not in use. There's a storage trunk at the front with gas bottles, tools and a spare number plate.
At the rear are lights and number plate. I've used 2 white minifig hands for stabilisers underneath.
I used Part No. 52501: Slope, Inverted 45 6 x 1 Double with 1 x 4 Cutout at the base on either side of the caravan. This allows for a slope either side of the wheel arch and space for the door while keeping the overall length to a minimum.
The roof opens to access the interior. You can see the layout in this picture. The kitchen is at the lower right, toilet is upper right and seating/beds on the left.
The kitchen is fitted with a hob and grill underneath, two cabinets on the right and a sink in the corner with a bull horn used as a tap.
On this side there is a tall unit next to the toilet door, some drawers and a fancy display cabinet. There are also drawers below the seating.
On this side there is more storage including a wall unit with glass door.
The forward end with the seating and also a little unit with a lamp on it.
Opening the toilet door we can see the toilet at the back with olive green lid, a shower drain in the floor and a sink and tap on the left.
the perfect vehicle for living on the run, I assume that's why they keep and extra license plate, to avoid the Lego police...
Very clever and compact use of pieces to pack it all in, in a realistically utilitarian fashion like we see in real campers. Great building!
