Hello and welcome to Airforums.com, Thorsby1! Very sad to hear of your wife's problem.
If you want help fixing a price for your trailer, I suggest you start a thread on the Trailer Values
sub-forum. You may be surprised at the help you can find there.
And I agree with Pat (pmclemore) that you can get your trailer in front of a lot of real buyers right here in our Classifieds, and for no charge at all.
Best regards and good luck,
