Jared, I'd take that Denali off your hands ;-)
My wife thinks I need to give up my beloved Audi Avant S Line for something with more ground clearance after this horrible winter, so I've been shopping for trucks and SUV's again, after owning many over the years. I had a 2007 Acura MDX that was a fabulous car, but it only tows 5,000 lb in a pinch. The Honda Ridgeline would be nice but the same 5,000 rating, not a "real" truck in that sense. Same with Pilot, Acadia, and almost all the crossovers. All have short wheelbases and are lightweight, not good for pontoons.
I've also looked at pickups and am kind of shocked to hear Keith say the Hemi struggled. I had the hots for their new EcoDiesel 1500 truck but I've never been keen on any of Dodge's interior designs (sorry Semper), and they're just now hitting the lots so no deals at all. They offer the EcoDiesel in the Grand Cherokee but it's only in huge money versions, they still depreciate like a rock, and I think they have a questionable reliability reputation.
I learned the VW Touareg, BMW X-5, Audi Q7, Porsche Cayenne all tow up to 7700 lbs (3500 kilo in Euro-speak) and have diesels available. Online reviews rave about how good the Touareg tows, so I'm looking at a used VW Touareg V10 diesel on Friday. It can pull large trees out of the ground with 550 lb-ft of torque. It's also pretty hefty so doesn't get moved around so much and has great brakes. I test drove a new V6 TDI Touareg tonight and loved it. It gets great mileage too, but it's just too much $$$ for as infrequently as I tow. I really wanted it to follow me home, but alas, it's not happening.
I suspect when all is said and done I just need add a truck to the fleet, but I really don't want yet another vehicle to maintain.
