PopRak is pretty cool, but will an AC unit really be able to operate at that angle to cool the upper area as he mentioned? I don't think so, but will wait for somebody that knows.
I'd say not very good from the looks of it. The top hard shell part is made with a plastic honeycomb (brand names Nida-Core, Plascore if you're interested in more info on the material)The honeycomb cells are basically dead air space so it does have some insulative value but it's not very thick so I'd guess R2 at best. As a boat builder, I've got a lot of experience with the material. I like it for what it is but it's not sold as an insulation product. The sides appear to be just fabric so next to nothing (like any tent). Bottom line - crank up the heater! 😁
Having done a lot of 4wheeling in my past that is just a Dana 60 set up for a Sprinter. Not that that is bad, but not really anything new. They are likely made by Dynatrac or some other large aftermarket axle builder.
PopRack needs to learn how solar panels work. Covering up your panels with recovery boards (well anything for that matter) is a big no-no and can take your solar input to zero (this obviously depends on the panels bypass diode configuration).
