I must be missing the point, it appears. I see the flat bars under the panels for and aft and it appears that the panels are bolted to those bars. How do you have full access from the top with the...

That certainly sounds like the logical way to assemble it, but it just doesn't look like there is room to reach under to bolt the panels to flat pieces, but maybe the pix are a bit deceiving.

I assume the crossbars support the flat stock underneath the panels to support them, but are they bolted there also to hold them down? If so, how do you assemble this on the van? Or does it go up...

Smart move, using the known to be secure factory roof rack mounts is by far the most secure way to go, assuming good quality hardware is used to that mounting. It should also put the panels up a bit...

I really don't want to go excessive on this, but a single bolted center like that gives only one axis of adjustability. That would be across the van in this case. The roof of the van appears, at...

Those are quite large feet, and I assume flat. Is the roof equally flat where they sit?


We have heard of the solar panels falling off several new vans lately, maybe Thor?

The air dam is a good idea as air underneath can generate quite a bit of force.


I did the calcs (simple) to find out how much air pressure it would take to get to 450 # force on the underside of...

Just as a perspective point of reference.


A 20X40 inch 100 watt solar panel has 800 square inches of area.


Even 1/2 psi on that panel more on the bottom than top would put 400# of force on...
