    Push the gas pedal all the way down and find out.

    edit: kidding. I've gotten mine going pretty damn fast on dirt trails (<50mph anyhow). I wouldn't go that fast on pavement because of binding issues but...

    I'm sure the manual has a number though... I'm way too lazy to check.

    Usually been around 60mph is the top reccommended speed to shift the truck into 4hi from Toyota, but you can go as fast as the truck will normally go once in 4hi.
    Tight turns on pavement with 4wd engaged is not recommended as binding may occur.

    Personally, if you can drive 40mph+ safely, you shouldn’t need to engage 4wd at all

    You can drive as fast as you want in 4HI but you have to be under 60mph to engage/disengage it. Once in 4hi there's no set limit. People do crazy speeds offroad in the desert in 4hi.

    Although in most cases being in 4wd means you aren't driving in ideal conditions for higher speeds so that's something to consider.

    Just to give you an example, for 2nd gen 6s speed MT 5th is the highest gear you can be in 4H. The fastest you can go in 2H/4H 5th gear is 127mph.

    The owners manual has a section about shifting and what max speed is in 2H, 4H and 4L. Read it to see what your 3rd gen limits are.

    Driving in 4hi at freeway speeds is quite common in snow country.

    I run at 50-55 max in winter, if it’s safe to go faster, I don’t need 4WD

    That's the max speed to engage 4hi. Once engaged you can go faster than that.

    It does, marginally, in some situations.

    Just because you CAN do something doesn't make it a good idea. You're not supposed to be driving on pavement in 4X4 at any speed. If it is safe to drive over 25-30 mph you don't need 4X4. Even on wet or snow-covered roads 4X4 is doing more harm than good at those speeds. If you want to do that buy something with AWD.

    You must not live in snow country.
