Assuming your WD hitch is set up correctly it should do fine. Your trucks towing capacity is based on the weakest link of the total package. In other words, if you have tires that are only rated to carry 1,000lbs then that's all your truck is capable of carrying, whether it's an S-10 or a crew cab dually. I would install a trans temp gauge if you don't already have one. Make sure you have light truck "LT" rated tires and that your rear suspension doesn't sag too much with the weight of the trailer attached. Other than that Airstreams are known to be among the best towing travel trailers out there. I think your truck would handle it fine if set up properly.
