Here's the sides attached temporarily to the floor and frame.
And here is the sides with a temp top and my rack I built set on top.
Here are the placement of the windows. They were bought from a truck topper shop locally. Pretty inexpensive, too.
Lots of room!
Next I get to build the laminated sides and cut out the door. So as it stops snowing here and it ewarms up a bit more. Too cold out in the garage to glue anything up. But I am progressing! Thanks for all the info here on the forum. Everyone is so helpful.
