lego truck T2 MKII with lego lowboy trailer TR4 MKll with dolly loading hauler 6x6

After I built the T2 MKll truck and trailer TR4 Mkll from 2legoornot2lego, AKA Ingmar Spijkhoven, I decided to build his lowboy trailer. At that time the instructions were not available but after a while of looking at pictures and videos of it I find out how the gooseneck worked. I already knew how his suspension worked because I had the instructions for the TR2 trailer so I built it with some modifications. I also built a hauler 6x6 with the instructions of designer -han, AKA wuppiesoft, on YouTube. The instructions for the improved lowboy trailer with booster are available at: http://www.ingmarspijkhoven.blogspot.nl/
