One more piece of advice is to take a break for a little while. Don't mess with the truck for a month and come back to it. Don't look at it don't think about it just drop the project for a month or so. It's easy to get burned out on something like this when you are stuck and not making any progress for a while. When you come back around with some fresh eyes after not messing with it for a while you are less frustrated and you might be able to see through the fog and come to a clearer game plan.
