Personal opinion...low miles and you are in the rust belt...ask for $5500 and hope for $5000. I sold Big Ugly (my 55k 1008 on 38" Michelins) for $4750 in August. I was told by people who meant what they said that I'd be lucky to part it out and make $2k. Others thought $8000.
The market has changed on these vehicles over the last several years. 4 years ago I got RAPED by Alfa Heaven for Big Ugly but it was my fault for not doing due diligence on both the truck and those shysters. I could have gotten a better deal. The market was high, it looked great and smelled like a nice old Chevy truck. It was a 1 ton! Could have made my money back on the spot even but it was a decent enough truck, even if I overpaid for it. Within two years the gas prices shot up and the economy tanked so the value of rust free older trucks went down. I bought my rust free, great shape, well optioned '89 K5 last year in Seattle, WA for $1800. A few years before I'd have been lucky to get it for $5k.
Remember while rust free trucks are rare in the rust belt the economy sucks. Hard to find a guy willing to pay $7-8 for a 20+ year old truck anymore.
I put mine on Craigslists ALL OVER the state of Michigan (truck was still up there with a buddy after I moved south last year). Within 3 days a collector called and wanted to come see it. He liked it, waved cash in my buddy's face and we agreed on a price and it was gone. Done and over. I don't regret it. Sitting on it to get more for it would have just meant my buddy had to baby sit it and I had to keep paying insurance on it.
Also, when you advertise it, bring every aspect of what it is into the ad. CUCV, Chevy K30, M1028, low mileage, offroad machine, great building platform, mud bogger, rock crawler, rust free, whatever. That way Bubba who knows nothing about military trucks will see the ad and go "holy sheeee-it, a 1 TUN!" and Bob the collector will go, "wow, a low mileage M1028!" Maybe they'll even bid against each other.
Good luck.
