Chris, Sorry for your loss. As FiveORacing said NADA is a good source for price guidelines. I just sold my '04 1950 on Craigs List in 4 days. I hope you have just as good luck.
I know you said your heart is not in it, but maybe camping would be a good way of remembering him. We camped with my parents some, and today sitting around a campfire camping brings back a lot of good memories.. Just a thought.
