TC's are pretty cool. I love mine, but the more I think about how they're built the more I'm perplexed. I'm hoping somebody out there has a good understanding of a truck camper's structure and how it's able to support the weight that's exerted on it. I realize that the interior cabinets and components provide structural strength, but I have trouble wrapping my head around how the overhang doesn't collapse with the additional weight of those sleeping in it and how the lower box is supported and how the lower box supports the entire camper when it's anchored to the truck.
I've tried to locate a pic or drawing of a TC's aluminum frame, but have been unable to locate one. Finding one, I'm sure, would help me understand a little better how a TC's structure works.
Anybody else ever wondered about these things, too? Or am I alone?

Lance sent me a full set of plans for how my 915 is framed and built,it amazes me how the extended cabover stays extended with just wood framing.They have been building them for a long time,all we have to do is maintain them so they dont collapse,lol.I think as long as you dont have more than one partner with you in the north south bed all will be fine,lol...

The welded metal frame makes it easier for the cab over area. The old wood TCs had 2 by 6 or 1 by 6, depending on wall thickness, running from the bottom front of the cabover to several feet back into the camper section.

Like Kerry said go to the Northwood Mfg site and select brochures and then part way doww they have a picture of the aluminum frame of a camper it is a small picture but it is a PDF so you can magnify it and get an idea. I don't think it looks very strong in the picture but by the time you add the interior and exterior wall material it adds a lot of strength to it.

Thanks, guys. Yes, those pics do help, but I'm still not seeing what's supporting all that weight in the overcab area, especially on the bottom. That's really the one thing I have trouble wrapping my head around. I guess I need to be an engineer to figure that out, LOL.
AF used to have a nice structural print in the 2010 brochure. Not sure if they still show the same print in the newer brochures. They even had a close up of the lower cabover corners and how they beef up that area for support. The whole diagram was rather impressive.
