I had a 2007 Ford Escape 4x4, 6 cyl. for four years. (lease) Rated for 3500 lbs. towing capacity.
It towed our 16 foot Legend with no problem. Even towed my 5 1/2 x 10 hd utility trailer with 8 x 8 heavy ice hut strapped to it. No issues.
Recently bought a 2008 Jeep Grand Cherokee 4x4 with 3.0 litre, 6 cyl. Mercedes diesel engine. 7400 lbs. towing capacity.
2007 & 2008 are the only years they put this engine in the Grand Cherokees.
Towed my friends' 16 ft. Sylvan with 60 hp Merc. a couple of weeks ago. Sometimes I forgot the boat was even back there.
This vehicle is great, but unfortunately, the resale price on these trucks is very high.
2005 and 2006 the Jeep Liberty came with a 2.8 litre 4 cyl. diesel and are much more affordable. Might be something to consider.
