I am in need of a cheap tow vehicle (suv) for a 5k pound boat. The two vehicles I've narrowed it down to is a 2001-2008 suburban/Yukon/Tahoe or a 2001-2007 sequoia. Reliability is pretty high on the list and I've had relatives with both of these that went to 300,000 miles. I've been using my 80 series but it's starting to show its age. Any advice would be great. Thanks
