I had a 2005 GC with the 4.7. Was a good puller but not the best gas mileage. I got about 19 on the highway and 12 towing an 18 foot alumacraft. Wasn’t the best at stopping with the boat behind it. I liked the vehicle except I had a few annoying issues with it. The stereo wouldn’t eject CDs, the lights in the center console went out one by one which required the replacement of the entire section of the dash, the rear windshield wiper arm fell off, and one door speaker blew out 4 times in the first 3 years. There were probably a few other minor things I’m not remembering.
All that being said, it was comfortable to drive, and would pretty much go through anything. It had the full time all wheel drive. I pulled a 20 foot enclosed trailer with snowblowers and an ATV through an 18 inch snowfall and never came close to getting stuck.
I have a 2 person Clam flip over that fit in the back with room to spare, and my strikemaster would fit along side it. I think I hauled a buddies older otter cabin once as well if I remember correctly.
