It took me four years to figure out, but if you get some good tarps, zip tie them togther and then basically make a cover for the tent that's well staked, it will be much less dusty. Also, be cogniscent of your surroundings. Can you use tall vehicles as a wind break? Which way is the door facing? Can you fashion an entryway to the door? I have a van so my tent faces the sliding door at about a 45 degree angle and then I use a tarp as an extra barrier.
Honestly, though, if you have time and thr receipt, I'd consider an exchange.
