Thank you to everyone, all the replies have been helpful.
We have a diesel Excursion and a diesel F-250 so no problems towing one.
NADA said Low book was $21,000 & High book was $25,000 which blows me away since you could buy them in 2010 brand new for under $20,000!
Doesn't matter because the bank says $16,500 and I offered $17,000 for the one we have our eye on. I'll be going to look / pick it up after the first of the month.
First trip to FL already planned either way on the 16th of April, pop-up or Loft I'll be in PCB / Destin area with the family
