Just give it a try yourself. Home depot etc will make semi accurate cuts for you if you go in with a cut list, then if you have a woodplane you can make it all fit.

I didnt think I could do it either, but here we are, 4 boxes later and 2 more being built this weekend for friends.

Goodluck.

 

i got a box for $20 at XS cargo, and yes its carpeted, and it doesn't leak, but thats about it.

 

and there is a sticker on it that says "made in canada" ruh kakakaka

 

If you get all the measurments and go to HOME depot buy the wood and for a buck a cut the do ALL the cuts for you.
Then you put it togeather...
