Their double coat is their insulator, you shave a double coated breed and it can ruin this mechanism. While their double coat does well to keep them warm in winter, it also keeps them cool in summer.

I completely disagree. I've seen so many people say this, but have yet to see any proof of it. How many long-haired, double-coated wild animals do you see running around in very hot climates? And just look at the coats of the dog breeds that originated from hot climates--pharoh hounds, greyhounds, basenjis, Ibizans, Rhodesian ridgebacks and Australian cattle dogs, just to name a few. The only desert breed I can think of with remotely long hair is the afghan hound, but it's a single coat. That has very different insulation properties than a double coat. You try running around in two layers of snug-fitting thermals in the summertime and see if makes you feel cooler.
My neighbor shaves his Akita in the summertime every year, and you can tell the poor dog gets so much relief from it. Before the shaving, the akita wants nothing to do with moving. All he wants to do is sprawl on the tile and pant. But after the shaving, he is happy, playful and prances around the house. The same was true with my aunt's malamute.
If your dog is in the direct sun a lot, I can see where shaving might cause some problems. The dog probably isn't used to having the sun hit so close to the skin. But if your dog has access to plenty of shade, I think that there's nothing wrong with shaving.
EDIT: Just wanted to post that, since it's only 82 degrees, you might want to give Bodi a chance to get used to the heat before you consider shaving. That temp is not really very hot. Shaving is more common here, but it's much hotter. Our temps have already been 100 degrees or more for the past few weeks. I don't think I would shave my dog if the temps are only in the 80s.
