Hi Nanette, welcome to the forum.
Not sure if any 5.0's are in your neck of the woods, but Tammy at Escape would know for sure.
the 5.0 and the 19 are both quite nice. The biggest advantage to the 5.0 is the way the bed works, entering it from the end instead of one person crawling over the other (but that can be fun too
). I had considered that, but did not want to have a pickup dedicated to the trailer, when an SUV would work better for me the rest of the time.
We are very please with our 19, and there is not a road out there that I would not take it, where someone with the 5.0 would go. Combined with our Pilot I can maneuver in some very tight places.
