6.6 bed without a doubt. I'm on my second one. Plus the 5.6 foot bed looks silly.

6.6 for sure...I wish there was a 8ft option with a screw 150.

Get what works for you. We all have different ways we use our trucks.
I prefer 6.5 bed but that is what I want.

I'm just a regular guy, i'll go with 5.5".
Remember that SCREW back seats have flat floor and when the seat folds up, theres plenty of space to use there also.

I haven't been able to determine what the additional weight of the longer box is. I do know the 157" wheelbase has 50 lbs greater GVWR (7050 lbs) than the shorter wheelbase.

For me a short box pretty much removes the possibility of ever using a truck as a truck. I believe this is reflected in why they are extremely rare creatures in small rural communities. Hell I don't think I've yet fully adjusted from when there were nothing but 8' boxes.

Thanks for all the feedback. I truly don't do much hauling and my current 5.6 has been just fine. I did opt for the bed extender "just in case" i need it some day.

Mostly city driving for me anyway, think I will stick with the 5.6.

As many have said, it's personal preference. For me, I could never go with less than a 6.5' bed because that's the shortest bed that you can load an average sport bike into (straight-on, tailgate closed, so there's plenty of room around it for stuff), and when I need to haul 4 of them, one has to get loaded into the bed. I regularly use all the space in my 6.5' bed, love it for the combo of usefulness but not looking like a work truck.

I had a 6.6 in my last truck (2 door). Worked perfect for hauling my ATV's and dirtbikes. My 14' is a 5.6 screw.. I like the look better, larger interior (especially with the rear seats flipped up) and plus it fits in my garage. If I need to haul anything long, I just put the tailgate down. To each their own.

You are correct. The GVWR on the 6.5 box gets you up to 7050 lbs, but you end up losing 99 lbs of payload. I have a 2011 SCREW Lariat with the max tow and I found an 2014 loaded up exactly the same except for the long bed. My payload is 1715 and it's payload was 1616. I was kind of bummed because I was hoping to gain some payload.

I think the 5' 5" looks weird. I waited a long time to find the truck I wanted with 6' 5" box. I almost factory ordered.

The extra foot makes a big difference.
