That is exactly what I paid for my 1965
Safari a year and a half ago, and I looked for a year to get that one. Although, the one you are describing sounds to be in BETTER condition than mine. Seems like prices are are down a bit due to the sagging economy. Therefore, a better trailer for the same price sounds about right.
How is the floor, especially along the back edge? The '65 have funky plastic tail light housings that crack and are prone to leaking.
Got any Pics of the side window damage?
The vents are fairly easy to fix, or replace with a Fan-Tastic model.
