Well, The Bear got to see it today. Of course she liked it, but without a point of reference she really didn't know how much or little. The seller told us that someone had looked at it earlier today and said they would take it, but he had no money in hand, so we know that means basically nothing. I took a picture of the original sticker with all the options and used them on the NADA estimator. I didn't really understand all of the option choices, but I came up with a value just under 25K. The tire date codes are 3600, so it appears that these are the tires it was born with. Furthermore, the fronts are Goodyear G159 which I understand are rolling bombs, on top of being 17 years old.
So, armed with this info this MH seems to be worth 20-22K. Since we are in no hurry we will probably leave it be for now. If he still has it when winter rolls around I may offer him 20K. Most likely someone else will grab it and start enjoying it right away. If that happens I'll be happy for them.
This forum is a great resource. Just the tire advice saved me thousands, not even considering the safety factor. Thanks
