[Land-speed] Tires,Mileage,etc/non LSR ?

[Jim Dincau]

     In 2006 I tried an experiment with my 2004 Dodge 2500 long bed crew cab 
diesel with a 3.70 rear a camper shell and stock tires. Not towing anything 
but with the back full:
Palmdale to Wendover at 55 MPH, 22 MPG.
Wendover to Palmdale at 5 MPH over the limit, 17 MPG.
Same route both ways through Bishop, Tonopah and Ely, calculated by miles 
traveled and fuel pumped. Pushing all that air is expensive. My brother 
wants to know if we are going to try 45 this year. I am not that patient, 
although in the past with some of the rigs we have had 45 MPH would have 
been flat out.
