The funny thing about taking a truck apart......you don't have to remember where anything goes, or even know what it is.
To put it together is a whole different story.
I would suggest making it a bunch of smaller projects instead of one large one. That way you can drive it inbetween, and it isn't as discouraging or overwelming.
One thing that I have noticed is that it can be a lengthy process. If you have to continually shuffle the project around to make room for the things that HAVE to me done, parts get lost or harder to find. Many projects never get finished that way.
Good luck and keep it fun.
