Just got my bricks and its 99% complete, just missing some flat tiles but thats no issue. The truck is not modded at all so the original ladder section can be removed and added as you wish.
You were right it didnt corner too well so I moved it all a stud back. Later tonight I am going to mod the trailer section so it only includes 1 axle and see how that works. I want to try to keep the front as stock as possible.
