1994 Dodge Falcon 190 Class B Van is it worth 8000?

[Assyrian_Elvis]

Hey guys unfortunately my 97 Coach house van burned in an accident at the mechanic shop when they were testing the fuel pressure and fuel pump. I live in Little Rock Arkansas and Im looking at a 1994 Dodge Falcon 190 model 19foot with the 5.9 liter engine. It has 89000 miles and looks and runs very good. The only issue is the owner is trying to get the onan microlite 2800 generator fixed. The owner says the generator works but its not producing enough wattage or electricity to power the items in the coach. The owner also said he intends to fix the generator and will not take less than 8000 for it if the generator gets fixed. I did a nada value search and it said it was worth 6900 high retail. My question is is it worth 8000? And how much should I pay him if he doesnt fix the generator or includes the generator with the van not working or excludes the generator from the van.Here is the link to the van

These vans are very hard to find especially here in Arkansas. If anyone knows a better deal please let me know. Im looking for a nice class b. I have about 10000 bucks coming from insurance settlement.
