I am thinking about trading my '88 Ford F150, longbed, good shape, needs a tune-up and a tailgate. 131K miles. And I will get a 18' double axel car hauler trailer, in excellent condition, and $800 in cash. I priced similar trailers in this area and they are priced at around $900. So, this makes his trade to me worth $1700 and he gets the F150. I have been running an ad forever on the truck and nobody has offered me more than $1800. Thoughts?
