Not quite.
No external support. All on our own.
My original post, I am not saying, not take tools, or spares.
I am saying, take spares, pack a tool box to get you home. You don't need a complete tool box to rebuild your motor on the side of the road.
Be realistic, do you really need that complete imperial set of tools? When your truck is metric.
Do you really need a complete set of spanners and sockets? Pack only the ones that fit your truck.
This what I am saying, not head out with no tools or spares.
I require all people on our 4wd club trips to carry 2 forms of lifting a vehicle..........
Case....(and it has happened on a trip I was on, names and places are changed to protect the guilty, and no it wasn't me

)
You're on a remote trip, say the Anne Beadell, travelling in a convoy of 3 vehicles. You have stretched out to keep dust down. You're tail end charlie.
You call the others that you are stopping for a pit stop and you will catch up to the others. You are now out of UHF range by the time you get back to your vehicle. A photo opportunity arises. This puts you further back. Now, this scenario has been played out many times not only on this trip, but others as well.
Damn, you get a puncture and not realising that it was flat, it's now shredded. You stop and change the tyre. Now you've got the wheel off and due to the terrain, it slips of the jack. You now are stuck, no uhf comms, the truck is on the deck and you now have to wait for your travel buddies to realise some thing is wrong and you haven't caught up and turn around (could be hours) or say you're travelling with your family and the scenario above happens but the rig has fallen trapping you under it. Do you have a second jack that the missus could lift the vehicle off you?
If you are travelling solo (which I mostly do) or with a small group, you need to carry everything.............and then some..........
