I'm sorry to hear about your husband! I would list it on a local classifieds. I had a trailer a few years ago that I need to get rid of and that's where I sold mine. If it's in god shape you might be able to sell it to a dealer too. You probably wouldn't get as much money but it would be faster! http://www.bradstrailer.com/contact-us
I am sorry to hear about your husband. If you can send me some more information and maybe pictures I will check with some of my clients and friends to see if I can help you get it sold. I know many avid campers. My contact information is firstname.lastname@example.org or 949 218-0280. I can even stop by and take a few pictures next time I am in your area.
