Looking at some Airstreams

My wife's uncle has inherited a small old Airstream and whenever we talk RV's he says how great Airstreams are. So, I really looked at buying an Airstream. They are poorly or not insulated at all, due to their shape storage is lacking at best, on the Airstream forums you hear complaints of people towing down a dirt road only to open the door to their trailer and find it full of dust, due to poor sealing practices. I believe that the old Airstreams were well made but they are not perfect, lack of storage and insulation just 2 factors.
As far as a discount take the suggested retail less freight and deduct 25% and don't pay a penny more.
Good luck.
