Advice on efficacy of custom, insulated Pop-Top and lift mechanism design.

Hey all!

I decided to start this thread because I wanted some advice on a custom "Pop-Up" truck camper that i've been designing for my 99' 4x4 F250 (Supercab w/ 6.5' bed).

The goal of this design was to build a camper with as low of a vertical profile as possible while driving, but with the ability to pop up into something tall enough to stand in when parked. Also, because much of my reason behind building this camper is having a warm place to sleep during those especially nippy northern nights, it was critical that the design be well insulated. Because normal pop-up campers use a canvas material as the "walls" of the pop-up section, this would clearly not do as any heat generated inside would quickly be conducted through the material and lost.

So after doing some searching online, I found this website (poptopcamper.freehostia.com) in which somebody had built a pop-up camper with solid walls. Unlike the old Alaskin Campers, this design did not involve the walls sliding up, but instead had two of the walls hinged to the roof and top plate so that the roof would swing into place. On the website, he includes a of the mechanism in motion, which I would recommend checking out.

I set out to design something similar, except instead of using simple 1/2" plywood for the walls like he had, using 2x2 framing insulated with R10 worth of XPS foam. There were some challenges in doing so, but I finally came up with a design that would seemingly work. I feel relatively confident that if the walls were properly braced and secured when they swung into place that the structure would be solid, and have a plan to wind and waterproof the structure as well. If any of you disagree with the core plausibility of building such a structure, please do let me know however, as I have never built a truck camper (or anything quite like this) before.

If, however, you do think that this idea is plausible, I need help resolving two issues:

1) What can I do, if anything, to change the design of the roof in order to remove as much weight as possible

2) What mechanism would be the safest, simplest to build, and least expensive way of lifting the roof? Page two of the "Pop-Top Camper" that inspired this build includes details for the roof lifting mechanism used in that design for reference.

Thank you all so much, I look forward to the feedback!

Using 2x4's and 2x12's and 1/2 inch plywood is way overkill - the camper will be very heavy and hard to open.

I would suggest looking at other threads here on camper construction and perhaps even boat building. Threads by "IdaCamper" and "Paul Jensen" would be best.

There also is a company here in WA state that makes rigid panels up using foam core and thin plywood with a inner grid of interlocked wood strips - check out www.singcore.com for ideas.

That type of lifting design has been done by many people and it can work well - but one of the big concerns with any design is keeping it water tight going down the highway. The first design is unfortunate that you can't use the space over the truck cab.

I have a pop top with canvas sides and in cold and wet conditions there are serious problems with condensation because of the lack of insulation. I am therefore thinking along the same lines as you. The best design I have seen so far is here http://www.sandkorn-leichtbau.com/index.html . Unfortunately it is in German but the pictures are self explanatory. The advantage of only lifting the rear is that it is fairly easy to build, it is much easier to keep the front end watertight when driving and it is much easier to lift. It is also more stable in windy conditions. You can use a cabover at least to some extend but it is not as roomy as a design where all 4 corners lift.

Our engineer in Germany has designed and build several insultated pop up and lifting roof expedition trucks. His service comes at a cost but you would know that you would have solid expertiese backing it. We could supply you with the panels and extrusions for a quick and easy assembly.
