HI Ingmar,
as promised pics of my build. I used the color scheme of the 8285. I'm completely redesigning the truck to 12x12, full suspension, Sbrick, full remote, etc. but that will follow if you're interested. The changes I made to you're wonderful trailer are; 4 axles, axle 2 and 4 lift, different axle with stop and pulley disc to suggest a brake disc, longer deck, Longer neck, 2x Sbrick, motorized winch with integrated pulley, extended rear frame for extra support, red/white markers changed to trans orange/clear, LED PF for rear light, small change to the bottom to group all the PF cables.
Please let me know what you think of my version of your creation
