Good advice above. I have heard that ford is equip'ing vehicles designed to tow with 5000lb hitch assemblies. How stupid is that??? you need to check. I would also suggest the expedition if you can get over how stupid it looks. It is truly one of the ugliest SUV's ever. The older ones look like shoe boxes and the new ones look like station wagons not to mention the squat in the rear end when you hook up your boat.

That being said, i have a Tahoe which looks a whole lot better but i am not going to say buy a GM either. the 5.3L i have works just fine for my boat, but i don't think i would be towing a 22' or 23' boat with it anytime soon. I would opt for the 6.2 and longer wheel base of the suburban.

To be honest, i too am looking for my next tow vehicle and i am NOT impressed by ANYTHING that is out there right now. I am still not sure of the longevity of the 3.5 ECO, the AFM issues with Chevy/GMC, the poor performance and gas mileage from the Toyota 5.7 and the low reliabiltiy ratings with Nissan trucks/SUV's.

I guess if i had to choose it would be the 3.5 ECO ford. But the nice thing is i don't have too. I am waiting for someone to build something decent. There is no doubt the toyota would be reliable but its old old old tech since 2007, and we had the sequioa. Seriously poor gas mileage and lower tow ratings than its domestic competition. It was a reliable SUV but i never saw over 17 mpg on the highway (not towing, light load), towing i was under 9 mpg. The sequioa ever with tow package we had was 6600 lbs.
