I have a new F150 4x4 with the Sport Package, but without a locking differential.
I will seldom use this truck off-road. Occasionally we might get in sand or gravel exploring a river access. We will get in heavy snow maybe 2 or 3 times a year.
98% of the time we will be on hard pavement.
How capable is my F150 in snow or mud without a locking diff?
Have I made a mistake by not getting an FX4, or will I not even miss being able to lock all four? I will always be running street tires, the OE Goodyear Wranglers or replacement Michelin LTX A/S tires.

It won't be as capable in mud as the locking diff, and not very capable with street tires so if you're looking for recreational type off roading you should've got the locker and appropriate tires. Dunno what else to tell ya.

IMHO, asking this AFTER you buy is senseless.

You have a 4x4. Based on your expected usage, you will be fine.

Common sense will take you farther than a locker and meaty tires. My first truck was a 99 ranger. No locker or fancy electronic braking limited slip. I was in highschool and couldn't afford a lift or decent tires, but my friends had jacked up keeps and full size trucks. I could go everywhere they went. Had to choose my lines a little more carefully and use a little more throttle when I couldn't, but I never got left behind. And some of these excursions lead to water and mud over the tires, off camber ditch crossings, and the steepest hills we could find in eastern NC.

Now do the locker and nicer ties make it more capable in the hands of a skilled driver? ABSOLUTELY! Should you stay home because you didn't get them? Absolutely NOT!

I've been all over Co in mine and have not needed to lock the rear yet. You'd be surprised how far you can get with 4x4 and traction control. I don't rock crawl in a 1/2 crew cab truck so there is that.

I think you are going to be just fine. Enjoy your new truck, and don't sweat it.

This is the very best post I have found that describes the various systems and options; although its in the older (09-14) section I believe, it is still applicable:

My buddy with his street tires and 4x4 thought he'd be fine as well, until he got stuck in wet slippery grass..LOL

Tires play a big part in this.

Wait, whut? Lock all four? Tell me more!

Ain't nobody hyur got that, Cooter.

ELD: I got meseff that l'il gem - had it fer a year and, other than testing it initially to see if it worked, I ain't found the need to use it since. Fideen Schport 502A Larry-At fer x fer, wif twankies an' Hankooky ATM's ( dang good tahrs ).

But - better to have 'er and not need 'er than to need 'er and not have 'er

Whoa, I missed that...guess we all did. What MGD said: No stock configuration of the F150 allows for the locking of all 4 wheels.

My question though, is does the traction control work with the FRONT wheels in 4wd? I assume not, but if Ford did allow the traction control to work with it, that is as close as you could get to a "4 wheels locked" situation from the factory.

The combined efforts of AdvanceTrac, Stability control and Traction control utilize all four wheels.
