Thanks all for the fantastic feedback!
Rustic Eagle, I appreciate the info and link...
After research, scales, fluids full - fluids empty... I bought a new 2014 Ford F-150 Ecoboost with twin turbo and heavy duty tow package - I had the opportunity to upgrade and felt it was the best way to go.
Now I have the best situation possible.
The DW took the yukon and hauls her horse trailer - so win - win for both of us.
Again... I so appreciate all the feedback and response.
Hitting the road for two weeks in a few days and looking forward to reporting back and how we do.
