I guess i'm confused (not having ever hard all-time 4x4)....why the issue? You can engage/disengage it on the fly at speed so essentially the only difference is turning a nob when you need it, and leaving it off when you don't.
There's more difference than just turning a knob. With full-time 4WD, if any wheel begins to slip, torque is redirected from there to wheels with traction. With part-time, if one front AND one rear wheel are off the ground (as when crossing a diagonal gully) or if those wheels are on very slippery spots with no momentum, you might be stuck unless the locker is engaged. Not the case with full-time; if even one wheel has good traction, it keeps on moving. The TFL Off-Road You Tube channel demonstrates this by putting various combinations of wheels on rollers to simulate low-traction situations. I don't have my 4R yet; can someone educate me? In 4L will MTS or crawl control re-direct torque? It appears that A-trac has been removed from the 6G.

Our Jeeps have been my wife's cars as the 4R will be. When it's slippery here in Northern MN I don't worry when she drives to town. The Tacomas we've owned didn't give me that confidence. Training her to engage 4WD on the 4R will be easy; if she can't get going, she'll remember to engage. But will she remember to disengage when the road is dry?????

What tires did you have? Were they 4 peak snow rated? Most of the tires Toyota puts on the new 4Runner are not snow rated and Toyota also says you can't put snow chains on tire size 265/70R18 which is the standard size for the OR and ORP.
Is that in the manual? I don't remember tripping across any recommendations related to chains, but I will look for this later

Below is the page from the 2025 4Runner Owner's Manual with the information about not using tire chains on 265/70R18 tires which is the OEM size for the OR, ORP, Trail Hunter and Pro. The ORP is delivered with Falken Wildpeak A/T3W A 265/70R18 SL tires which do not have the 4 peak snow rating and the SL load rating is for Standard Load with no extra reinforcement, thus not a reliable off-road tire. What is needed is the BFG KO3 LT265/70R18 with a C load rating. Proven very tough for off-roading, 4 peak snow rating, and great reviews. BFG has this size with a very stiff E load rating. Sometime in 2026 BFG plans to release this size with a D load rating. Their schedule for releasing more tire sizes/ratings does not include this size with a C rating which would provide a less jarring ride than the E and D load ratings. We need to get lots of people to get BFG to add the 265/70R18 Load rating C tire to their plans for the KO3.

Sounds like you need the 4Runner Limited that allows you to select full-time 4WD.

Thanks. That's interesting. I don't think I've ever seen a stock vehicle not recommended chains. I've got a set of KO3s and a set of KM3s for my Jeep. I've been impressed with them in ice and snow. I'll put some freeway miles on the 4Runner stock tires this summer before I get new ones, but KO3s are probably what I'll get.
