Callen Style Truck Campers

[yj4roks]

Hi guys,

I am in the planning stages of building a Callen style truck camper. Since they are gone and can't just go take a look at one, I need help from the forum. At the moment I am curious how the back doors latch for security? Is there a "door sill" where a latch can catch at the bottom, or is the bottom free where someone could ultimately pry it open?
I visualize a T-handle that when turned slides a bar up and down to secure the door closed.
Pictures would be great if possible.
Any help would be great.
Thanks,

The left door without the handle has a simple slide bolt on the top and bottom that go into a supplied hole.
The right door with the handle latches onto the secured door.
Not really a super secure setup.
Lots of guys straddle the doors with one of those industrial strength locks you see on commercial vans.
Maybe somebody on here can post a photo.
I've had three Callens in past vehicles.
