[VAC] mileage while towing w/ diesels

[John and Jodi Guerin <guerin3j@xxxxxxxxxxxxx>]

I've heard conflicting reports regarding average mileage when towing with a 
diesel rig. Knowing how much folks seem to enjoy conversing about their 
towing rigs I thought I'd ask. What kind of mileage can one expect from one 
of the newer Turbo Diesel trucks, both unloaded, and with your favorite 
shiny, silver travel travel in tow?

Looking forward to the responses.
Thanks in advance.
