How much difference is there, and how much would I save on price?

 

Maybe 1 mpg. Added weight is about it. Not much honestly. The mpg difference comes from tire size but on the newer trucks they all have the same size tire regardless of wheels size. Overall height is pretty much the same

 

try here Compare Cars Side-by-Side

if you plan to drive in winter conditions forget about a 2wd truck...they are useless.

 

Also gear ratio, my 99 z71 has 3:73 and my friends 04 2wd has 3:42. Gear ratio plays a part in it too. I am not sure of newer trucks though.

 

I've had my 2014 CrewCab 4 X 4 1500 for about two weeks now. The stock gear on the rear is 3.08 ratio. With conservative driving habits, I am at 21 MPG

 

nice truck for highway driving, but that high gear ratio would suck for towing my 16ft contactor trailer.

 

As to OP's topic question, I have one of the larger rigs,

a 2500 CCLB. BIG difference in gas mileage here. Closer to

3 or 4 MPG.

The 308 gears, great on mileage, and they save a lot of engine wear.

But take it easy with loads. You could snap an axle.

The benefit to 4WD, in many instances, is the package the truck

comes with. Many times you get the lift, and other options you

don't normally see with 2WD, without custom ordering the truck.

 

I try to buy vehicles that I can get my money out of when the time comes to sell it. Its hard to sell a 2wd truck.

 

it's for my dad, he's 63 and this will be his last truck that he buys, I told him to order one, good luck trying to find a 2wd truck in new england

 

I showed my dad your post. He had a good laugh. He's 86.
