ehh, not really… most dealerships RATHER you finance, or so ive been told… however, you can never really embaress a salesman as you haggle them and then they go and haggle there boss lol
Best bet is to look up the EXACT truck, options, mileage ext on KBB trade in value… 90% of the time thats what theyve got in it… add 1,500 to that price and thats what your first offer should be.
