to condense the size of the rope when rolled up, you should click one, then select all and put it on no self collision. fun though. you should make a winch or something :]
allright, i like the design of your truck. i must say it looks pretty cool. but you need some tips on the mechanics. alright, so pretty much, it needs to be all four wheel drive (idk if you did that or not, to me it didnt seem like it) and then also, you need to have more travel, and more speed and a lot of power to get up those hills, but not too mich to where you jump like all of it. but other than that, its good.
