Things You'll Need
Instructions
Attach a 4-by-8-vehicle baseplate on top of a 2-by-12 baseplate. Place a 2-by-1 baseplate in each of the four corners so that the left and right sides are even.
Place an 8-by-1 baseplate on top of the left and right sides, and a 2-by-2 baseplate with ball peg on the front. Fit a 2-by-2 wedge on the front of the piece, and two, 2-by-2 reverse wedges along the back, so that the edges are even all the way around.
Fit a 2-by-3 baseplate on the reverse wedges, then a 1-by-6 baseplate on the side. Fit another 1-by-6 baseplate end to end with the first, so that the piece overhangs next to the front wedge.
Place another 1-by-6 baseplate on the front of the opposite side, matching the overhang of the last one.
Fit a 1-by-4 and a 1-by-2 smooth top baseplate on the remaining pegs on the side. Snap a 2-by-2 block into the center of the trailer, two pegs from the back.
Place a square windshield at the front and back of the trailer, then snap the shortest 2-by-1 wall pieces on either side of the front windshield.
Place two clear wall pieces side-by-side next to the first wall piece, along the only remaining side with pegs. Sit another 2-by-1 wall piece next to these.
Snap two 3-by-1 baseplates on either corner of the front windshield, then a 2-by-1 baseplate in the center of the front and back windshields.
Place 1-by-1 jeweled pieces on the back corners to simulate tail lights, then 1-by-1 flat top pieces on the sides of the wall beside the window. Add a 4-by-3 wedge to the top of the front of the trailer, and two 1-by-2 wedges back to back on the rear of the trailer.
Sit two clear wall pieces next to a solid wall piece, then join them with a 6-by-1 baseplate on top. Attach two 4-by-4-hinged trapezoids to the corresponding hinge base. Attach the hinge side to the 6-by-1 baseplate.
Fit this piece onto the trailer so that the wall pieces close in the window and the trapezoids complete the roof.
Turn the trailer over and fit a 2-by-4 baseplate to the front of the base. Place two 2-by-2 wheeled baseplates behind this one, then snap a 2-by-1 reverse wedge on each front corner.
