First off, know that the desk area in the rear of the trailer is not the standard floor plan for this unit. I don't know whether it was a factory mod or aftermarket.
The "tow package" valued at 3K, unless they are including a Hensley there is not way it's value is 3K, maybe 1K.
NADA list the unit at 22860 to 27570 (that was with me adding what I fugured was the way it would be equipted.
So price is in the ball park., But resale might suffer as not all would want the customized rear end.
Hope this helps.
