Are there any rules of thumb when going over rocky terrain about what line to take?
E. G. I've heard that you should always take a line so that you drive over the biggest rocks with a wheel, rather than around them since it lifts up the entire chassis, giving you more clearance for rocks.

Re: Line when rock climbing
I think visualization of where the 4 wheels will run, and what the car will do because of that line, is key!

Re: Line when rock climbing
This is not something that can be easily described in words. You need to actually go out and do it and even better watch others do it so you get a feel for what lifts where and by how much.
The first rule of thumb is get out and plan your line especially for uphills. Get someone to guide you if possible. Discuss the line with them. I have done trails I would have considered downright impossible with an experienced guide ahead of me.
The rule of thumb you mentioned is commonly mentioned but it is not always the correct thing to do because there are too many factors at play. I know because it cost me a smashed left rear fender. Granted it was on a grade 4 trail made into a grade 5 by the pissing rain.

For a moment I thought we are now into mountaineering!

- Once the front wheels are over that rock, make sure it does not catch the sills (halfway between front and rear wheels)! I often choose a line which is half-way up a rock's side (provided it has no sharp edges)
- As Marius said, learn the geometry of your vehicle. Learn to accurately place the wheels. Practice with bricks on the lawn. See whether you can accurately drive over them with you wheels.Place bricks on top of each other to test the clearance at different places under the vehicle.
- Always try to straddle a donga/ditch, never put a wheel in it! Once a wheel is in a ditch, it is difficult to steer out of it, and the clearance is compromised.
- Never forget that your vehicle touches the ground in four spots only. Low spots/areas between the wheels can be ignored, high spots/areas have to be lower than your clearance.

Re: Line when rock climbing
No more rock climbing for me. Went rock climbing last weekend at Kungwini 4x4 near Bronkhorstspruit with family and friends.
1x Fortuner, 2x Rangers & 1 x Pajero LWB (Me) It was quite challenging at times and a lot of fun. Was it worth it ? I don't think so because my son ripped his sidewall so he is in for R2,500 or more.

Err, I think I'll stick to Sandton kerbs, some of those kerbs are really high and tricky, especially when you want to park right outside the front door of your favorite shop.

Re: Line when rock climbing
May I also mention some sub terrainian parking in the new high rise office buildings in Sandton.
You need to look at kerbs there as well because some curves are rather small but also you have to appraise the nett height in some spaces, in particular if you have a roof rack with some accessories fitted .
The hanging pipes under the ceiling are rather formidable and even if you clear them with 20 mm to spare it is an eerie feeling.
