I don't understand this hatred for unibody, i have NEVER seen one broken in half.
i literally towed 1500 pounds with a unibody Chevy cavalier for years and it did fine and now i tow 2000+ plus with a mitsubishi outlander
i also towed over 40,000 miles with a 93 subaru outback and that had 0 issues as well.
the 98 cav destroyed the 93 subaru and the 07 outlander destroyed the 98 cav, im really not sure what you people want that makes a suv so crappy, and all my pulls were mountains, maybe not outwest mountains but a bigger tranny cooler and i would have no concerns.
no one is expecting 10k towing out of a small suv, even though i thin the grand cherokee is around 9k.
dully to pull a popup comes to mind.
