You are fine, the traction control works wonders. With your driving style a locker would be useless.

For someone who does a lot of rock crawling absolutely it will benefit. But even in sand, the key is to keep the speed up, where the locker will disengage automatically anyways.

 

I've only played with my locker also, to get a feel for how it works. Played with it and traction control last winter to learn all the different capabilities before I really needed them.

I got the elocker for 3 reasons: 1) IF I tow a boat for the slimy boat ramps, 2) pulling stumps out of the ground, and 3) never hurts resale.

 

I had 2004 Z71 with the G80 mechanical locking differential previously. Once engaged, I could get through a good amount of much in 2WD without needing 4WD.

On my 2015, I opted for a 2WD with a locker. I've only tested it once on a gravel road. The traction control on these trucks is impressive. Only concern I would have is extended use and the wear and tear on brake components.

 

It is a factor and materially less grip. I had a 4x4 wo locker and with. Big diff. also you need 4x4 far sooner versus just pulling the button out. not a huge loss in ability once in 4x4 if you work around it and avoid very low traction situations if possible.

 

You didn't make a mistake. For the money the locker is worth having, but it wont make or break it unless you intend to do some serious mudding and such. I think what you got is just fine for that use.

Generally speaking even 4x4 is overkill for a large number of people, especially outside of the snow belt. Def not knocking people who get 4x4 who really don't need it. It's their money and of course better on the resale side since it is what people want. It just kind of amazes me that over the last couple decades or so it seems to be evolving that people think a truck would get stuck in a rain shower without 4x4, even using it as a car and not truly going off road or anywhere they wouldn't in a normal car! Again though to be clear, it's def the popular choice and not knocking the norm, just stating that it's not near as vital as some people like to believe.

 

I've seen my share of 2wd trucks with one wheel spinning on wet grass.....

Today's trucks with traction control tend to work better, though sometimes at the expense of tearing up someone's lawn. I have to admit I got 4wd for snow, etc, but after this past winter I could tell it comfortably handled slushy roads in 2wd where I would've put my old truck in 4wd.

 

My last truck was a Ram Power Wagon. Those trucks have front and rear lockers. I also had beefy mud terrain tires on it. I could take that thing anywhere, it simply didn't get stuck...

Then my tires wore out and there wasn't much tread left. I went into a friends field and was stuck in something I would have walked through a year earlier, despite locking the front and back. Tires are everything. Lockers help, but tires are more important.

 

This is my last truck which I would take offroad all the time. It was 2wd with an open rear end. I got stuck from time to time but only when I expected to. You will be fine without the rear locker.

 

Locker is unnecessary for snow. You might miss it on a sandy river bank, but I doubt you would get stuck without it.

I've only used mine when packing the ruts on the jump faces on my MX track. Works well in the sand for all the starting and stopping. I never use it anywhere else. I could see where it would be useful on a boat ramp.

 

Had to put my last truck in 4wd a couple times to get my camper out of the yard...it was a 2011 with the locker but the locker could only be engaged in 4wd (but once in 4wd I didn't need the locker).
