2005 ram 2500 4x4 quad vs. 2006 ram 1500 quad 4x4

MPG's will be barely .5-1mpg different, if comparing GM 5.7 votecs in 1500's to my 2500. The thing about a 2500, is you have PAYLOAD, which frankly is more important than tow ratings. Even if the 2500 had a gcwr of 14K vs 15K for the 1500, I will recommend the 2500! I would rather be over a gcwr with a slightly impaired power wise correct chassis rig, than an over to correct powered under chassi'd rig. Been in both places in the past, will ALWAYS take the higher gvwr chassis.
