I'm selling my 02 E350 Superduty. Below is the craigslist ad for more details. Full disclaimer, it is 4x4 converted by Quigley, but she's a beast. You won't be disappointed.
Good looking rig. And I totally get the hunt for a 4x4 van that isn't $30-40k+. I didn't have that kind of money but was lucky like you were to find an empty 4x4 V10 for $17.5k. Put a platform in with a mattress and the adventures began.
GLWS - To be perfectly honest (and don't mean to sound negative) I think your a bit high on your price based on the condition of the van. But it always comes down to what someone is willing to pay. Bonus...your in an area like Calif and Washington people tend to pay more for a 4x4 van.
