Does anyone know about how much a '95 Winnebago Eurovan Rialto is worth?

There's one for sale in my neighborhood for a very low price.  It's been
sitting for quite some time but looks to be in decent condition.  I've poked
around a bit on the internet but the selection for comparison has been
minimal.  I'd like to have as much info as possible before I talk to the
seller, so any help would be greatly appreciated.

Cheers,

Jeff
