Yeah, $11k seems like a lot for a 1993 Dodge SMB. Dodge SMBs tend to sell for less than the Fords.
For camparison, here's a 99 Dodge RB50 that's newer, with less miles, for the same price (it's on the east coast, though):

I'll disagree a bit with Jage, in that I think 2WD SMBs pop-tops (not extended roof versions), Fords in particular, hold their value pretty well compared with their original price. Sure, 4WD vans command more, but they are also a lot more expensive to begin with. And you can easily add 4x4 to a 2x4 SMB if you want, as many have done.
