  Suburbans and XLs weigh a lot more than a Tahoe...thus the 'soft' ride of  
  the burbs.

  No. The 72s still had the in-cab 25gal tank...the first owner had the  
  dealer installed option of two saddle tanks installed. Total capacity was  
  a  bit over 57 gals...Even if the engine got a low of 10mpg, the mileage  
  range was 570 miles. With an Alaskan (crank-up collapsible) camper on  
  back, it got 14mpg when the wind was from the back. During 'Santana' high  
  winds out of the desert stopping 18wheelers and pickups with campers from  
  taking I-8 down the side of the mountains to El Centro, the Alaskan camper  
  was allowed to continue because of its low profile.
