Vs. a current model Burb, I have to say Excursion.
Solid axle, leaf sprung, Diesel, 5 speed auto . . . can be purchased in a stripped down version unlike the new Suburbans.
Oh yeah and as a 4wd it isn't mistaken for a 2wd like the new Burbs.
My brother had one for a few years while he was in Colorado, I loved driving it when we got together. Pulled like nothing else I've driven (less Semi's) was easy to drive and handled well off road for a stock rig with street biased tires. It is however much like trying to negotiate and Air Craft Carrier off road and in small parking lots.
Vs. an older Burb, the Burb hands down for reasoons to numerous to list, but cost of upgrades plays a hugh factor.
