Yep. 2 out of three lines(two to front, then one to the back two wheels) broke off when I accidentally bumped in to them, so I have a LOT of work to do before I can drive it around faster than 1st gear will allow. Seeing as how your truck is a LOT bigger and heavier than mine, it would be a whole lot harder to stop it just pushing in on the clutch and rolling to a stop.
