Note to Matt Plapp.
I am impressed with your firm's willingness to grow in your Airstream knowledge and abilities. Your response was timely and I wish you all the greatest of success. I have no doubt that if you all learn and try to understand the desire of Airstreamers to just find quality and honest (truthful) service locales, that you will become a rising star in your region.
Obviously you are aware of this forum, it has become a repository of much good advice for owners, (it also contains some incorrect and dubious advice). I hope you also monitor the other Airstream forums. notably the Val-List
and the factory board Airstreamer.
I have been told (or read) that no dealer is allowed to discount Airstream Factory parts, this is unfortunate if correct, as I would bet that you could develop an instant nationwide market if you did just that.
If at all possible do not overlook furnishing some "factory" training for a parts person who will likely remain with you for years to come. What an asset that "salesman" can become.
Lastly Matt if I may offer this advice as well; show the colors, i.e. put the Airstream name and logo on your business cards, on the techs uniforms, in the window of the shop, on billboards etc. The market (as you undoubtedly know) is growing and out there.
Oh and buy one for yourself, and encourage the rest of the staff to own one too. Familliarize with each era (pre 69, 70's, 80's and 90 to current) they're all different, some VERY
Best of Luck.
