I have a stock 09 Commander with Hemi and tow package. I pull a 25' TT which weighs around 4000 empty. GVW is 6000, although we are light loaders so I doubt it gets that heavy. I also have the P3 controller, weight distribution hitch, and anti-sway bar. Last month, I made my first journey over the Rockies pulling this trailer. I was really impressed with how well the Jeep did. The trailer we have seems like a good match for the Jeep as it has plenty of power and isn't screaming as it pulls up the grades.
