Saw this posted on reddit, seems like a pretty solid deal. Link to additional pics in the comments of the reddit post does appear to show some rust on the roof, so it could be worth a close look if interested.
From the post: Timberline 4x4 conversion, 4.6l gas, 215k on motor, transmission rebuilt at 183k, 200W renogy solar and isolator (no battery), fantastic van, led lights
I think I remember Timberline had that van on ebay about 2 yrs ago. Either that or one just like it. Thought it was a 5.4 though. Almost exactly what I'm looking for as a starting place. Would be nice to have power widows & door locks.
Messaged the guy twice with no response. ??? Also pretty sure that is not the van that Timberline was selling couple years ago. Same color and body style though.
