I think I've finally located my Tow vehicle of choice.
A 1999 F350 XLT Crew Cab PSD 4x4. It's a couple of hours away from here so I'm going to head out this weekend to take a look at it. Wish me luck.
This isn't the actual truck, but from the seller's description, this is what it looks like, right down to the stainless steel running boards, same color even.
