If that's the worst jump on it.
Our resident Airstream dealer, Andy, has pointed out that this sort of damage will fade with time. The properties of the aluminum that is used will tend to have the dents that are not creased pop themselves out with heat cycling. If he's correct then about 50% or better of what you see in that picture will proably begone in a year. THe cold of winter will cuse considerable shrinkage and next summers expansion sould do the trick.
As a example. The thin aluminum Hehr vents on our 59 look like somebody worked it over with a ball pene hammer from hail over they ears and there is no hail dents on the body at all.
