Id also get someone to watch out for you at the top, then you will get a clear run up the hill and no need to use the clutch.

Yes it does,if your on a hard surface you'll get transmission 'wind up' the first corner you come to, normally the open centre diff allows the front and rear axles to travel at different distances and speeds ( hence a 'differential' ) however as already pointed out a sort distance in low range is no issue, good luck!

In the days before t'internet, there was nobody to go to for different opinions. So when I got my first 4x4 the guy who sold me it said "whatever you do, do not select diff lock on the road. I've stuck to that and have never needed low ratio on Tarmac. As you can see, this situation throws a few situations together. I don't have the option of low ratio no lock, and I'm on Tarmac. I'm looking at this hill and I can hear that fellas voice "told you not to select diff lock on Tarmac!"
I can also hear my clutch saying "listen to the guys on Ribnet - They know what's best!"
I'm gonna go with Ribnet. To be sure of things I may put one of those stingers the coppers use at the top of hill as an Ethel trap

Yep, and it won't make any difference to the steering as the axle diffs remain open.

Indeed.

Don't think you're right on that one

The navara's don't have a center diff ( same as diff lock) so when you select 4x4 you can't go around corners or you'll wind up the transmission which normally costs big money to sort if you keep going and break it

I don't think its distance more the number of turns

n what makes you think the guy that sold you your first 4x4 knew anything about it, my experience of local landrover dealerships leaves a lot to be desired when it comes to the actual nitty gritty, they may well know hie to Bluetooth your mobile etc but how the real interesting stuff works, forget it! your 4x4 has a low ratio gearbox for a reason, so make use of it and reduce the wear n tear on the clutch n gearbox, running on Tarmac makes no odds it's still a steep hill n you're towing up, or down it for that matter! it's still excessive load when in high ratio, that's why some manufactures now offer the option of seamless change from low to high whilst towing, or 8 gears in high ratio auto boxes to reduce the strain when towing

the only thing I would add as a note of caution is that if you haven't used low box very often the sometimes they can stick going from high to low n back to high, so be patient with it, the more you use it the better it will get, my 90 will go from low to high at around 10mph without any indue grunching of the gears, does make life easier when towing, even more so if towing off road

Towing up steep hill / diff wind question

I use low box a lot with the 130 specially reversing
One place I go to I have to reverse down a 1 in 3 slope can't use brakes it just slides
Not used diff lock yet just plenty of right foot.

Wrong
The axle diffs allow there opposing wheels to turn at different speeds and distances (otherwise cornering would be interesting ) and ( this is the important bit ) the same applies for the front to back of the vehicle , the axles themselves also travel at different speeds and distance around corners , just look at your tyre tracks on a wet road, cornering they never truly follow each other hence a centre OPEN diff, otherwise you'd get transmission wind-up, poor handling, under steer, tyres scrubbing and ultimately damaged transmission - YES, locking the middle diff does affect steering.

Seeing as the front and rear axles have different ratio's,
locking them with the transfer diff will cause one axle trying to overtake the other axle,
usually the rear has highest ratio, and this can have an effect on the steering on solid ground,
I've experienced it myself, its not like you can't steer at all, but it feels like somethings gonna brake if you keep going.
