So, my question is: Who thought it was a good idea to build a Suburban that has no tow capacity?
A huge majority seems to agree that the Expedition is a far better tow vehicle than the 5.3 Burb. I would prefer a Burb but, I have owned sucky tow vehicles before and don't wish to do that again. Back when we were pulling a travel trailer the best tow vehicle we owned was an F-150. Then I thought a Jeep Grand Wagoneer with the V-8 would be the bee's knee's. Wrong!! Then my father-in-law gave me a Landcruiser. It was even worse.
All things being equal, Ford seems to make the best tow vehicles.
I like the Chevrolets but, for my money it looks like Ford is the ticket. I retired from a city that owned thousands of vehicles. When I retired the Ford's were better than the Chevrolets in every way, especially the amount of time that they spent at the garage. Fifteen years earlier it was GM that was superior.
