Partway through the panel design, got the shapes lasered and edges broken last week. This panel will get bead rolled to stiffen it up and more holes made for the dzus fasteners. And we started working on the hinge to make these sides operable, its been a big request so we are pushing the production forward a bit. It’s a real challenge to make the hinges work with our seal and tube placement and still clearing the camper bits, but it's looking like we’ve got it figured out with a pretty trick 8-bar linkage hinge...
Probably going with .080 5052. Should be plenty stout once beadrolled to maintain the seal, and is nice because its so formable. It's also got a really good corrosion resistance and with .080 skin will hold up well to branches and impacts.
Mocked up...
From the interior. Looking like a race car.

After reading your previous quote Im surprised you are using aluminum/steel? Would compositie not be a better material choice when it comes to thermal conductivity and weight?
The big driver was to avoid sleeping directly under an aluminum roof in sun or cold, so that is why we are using composite honeycomb paneling 'upstairs'. It has a PET film for UV stability (better than gelcoat), is pretty well resistant to impact. In case of running into a garage or something, we designed the upper panel to be replaceable without much mess. Its probably half an hour for someone to replace the upper panel if they have never done it before, and we will sell replacement parts for any component in the system.
We could use composite paneling for the lower, but toughness and impact resistance were definitely a concern. Something like carbon kevlar would be neat, but cost prohibitive. The sides will see a lot of abuse and long term durability, UV stability and maintaining a serviceable platform were all design considerations.
The aluminum paneling will be powdercoated, and that will significantly reduce the material conductivity. Additionally we are doing some testing with coatings that aim to reduce condensation/heat transfer. We have plans to release an insulation kit for the lower canopy as well as a winter weight upper tent side. We should have those ready for fall 2018/19.
Can't wait for the video tour.

Any update and pictures on the sealing of the two parts of the poptop?
Hey Phil, do you mean the top and bottom frame of the pop top?

Yes interested in the detail on how you are sealing the two halves of the poptop where it hinges.
No gasketed seal on those components, as we want the fabric to be able to breathe if put away wet. The fabric is a full 360, so it seals the leading edge, sides and rear.
The two extrusions overlap eachother on the outside to form a rain seal. Additionally, for any water that gets into the gutter on the lower extrusion, there is a drainage path with drilled holes to allow water to pass. Same on the top as well.

so there is nothing to prevent road water from getting the tent walls wet while traveling? the tent fabric must be really waterproof...
Personally I would not be happy with a free entry of water and air between the 2 frames while driving .
Also with a water resistant fabric .
moister always travels towards dry area .
NOT vice versa.
You might end up with a dry fabric ,but damp matrass
, which is even worse !
I would definitely put a sort of rubber seal between the 2 frames .
During some trips I also experienced 1 good week of heavy rain .....
I always plan for worst case scenario,
Just my 2 cents .

The metal frames overlap each other like a clamshell. We are testing the functionality of that seal while driving, of course if water intrusion is a major issue there, we will reconsider our decision and we have provisions to add a gasket if necessary.
The drainage/channel system is for when the tent is open and its raining.

Because I have made a few pop up before, would say that a vertical water resistant fabric is very difficult to get wet .
Should not be a concern , unless you go down the cheap way.
The back side is a different issue .
Different is the case of driving with the pop up closed .
There are pressure and depressure areas , depending on speed and air permeability of the interior that could suck in water and moisture, but also dirt and powder .
If you ride in sandy areas you will 100% come across dusty sand as deep as 50 cm .
In that case it's much worst then water !
From the picture of the aluminum extrusion I don't understand how they close ?
Sorry

The prototype is in Baja now, I am sure it will be driven through some silt beds. I'll keep you posted!
In the photo of the extrusions above, the aluminum on top is the lower rail. The one below is the upper. The "Tee" on the bottom left of the lower piece overlaps the "L" flange on the bottom right of the upper piece. Worst case, that seam will be easy to add a gasket. Time will tell, and this is why we are testing before shipping.

You guys are making me want to cut the roof off my 80. I am going to take some measurements this week and see about making that happen...
i'm also willing to make the drive up to montana! roof be gone! if you are adding 80's to the list, i'm happy to put my deposit in.

The owner of Maltec-us stopped by for lunch yesterday and what they are working on for EXPO2018 is going to be mind blowing for the poptop world. Having driven and camped in the 70 series below I can tell you I have never seen this level of quality in the US before.
