Speaking of fuel economy and traveling distance on a tank of fuel, do you guys have any info on the available fuel tank sizes for these trucks? I know that for my 1989 square body ‘burb diesel there were several available tank sizes.

Yes and no. Firstly, you will not find aftermarket, larger capacity GAS tanks. No one will make them, due to fear of the EPA. Secondly, as far as I know, all the 2500 Suburbans/Yukon XLs had a 26 gallon main tank (which held about 3 gallons in reserve) and an 11 gallon auxiliary tank (which would also hold 2-3 gallons in reserve).

If you go diesel, your FUEL tank options are pretty endless.

yep from what I have gathered the 2500 ( at least the 00-07) have the secondary aux tank.
