I have been priceing a loaded 4x4 quad cab , The 3500 single wheel one ton , is( FWP/list ) $1608. 00 more than the 2500 4x4 . there is a deduct of $783. 00 , which still brings it to $825. 00 more than the 2500 4x4 . What I want to know is what is the difference , What do I get for the $825. 00 more ? One dealer told me the only difference he could see was an extra over load & a 3500 emblem . You would think the bearings / brakes / springs / ECT would all be bigger , for that much money . Can any one help ?
