I have pulled my boat with all manner of full size and diesel pickups, as well as with a 2 door Wrangler, and nothing about pulling with my Gladiator feels like enough of a downgrade to regret having it. It's certainly thirstier and revs higher than larger trucks when towing, but it's rated for 7K towing as configured and has no problems getting up to speed, braking, or maintaining control with my bass boat or travel trailer. Mine is equipped with the 3.6 Pentastar and 8 speed automatic transmission. I knew going into it that I was getting a wrangler with a bed, but that is exactly what I wanted out of it and it has surprised me with its capability. You'd be hard-pressed to find someone else at the ramp with the roof off their truck.
Say hi if you see me at Wise County Park in Bridgeport, that's normally where I can be found on the weekends. I'd be happy to show you around the Jeep!
