I do not know how many Airstreamers know about Camp Freightliner offered at the factory in Gaffney, SC. This is a MUST for Freightliner owners, a wealth of information for a two day school that only cost $100.00, free parking in back of service center. It is what you DO NOT know that will get you. A NEW unit sitting on a dealers lot needs ATTENTION prior to purchase. You need to have it completely serviced with the Freightliner M3 service. Check out the Freightliner web site, freightlinerchassis.com for all the informatin.
