Most off-road handbooks recommend that you never venture alone into the back country. You should bring at least one other car with friends. It is called the buddy system.
I personally think that is not really necessary.
...you own a well maintained SUV -
...you have decent driving experience -
...you use common sense while driving -
...you always have a cell phone aboard -
...you carry a satellite phone and a GPS in remote areas.
Beyond pavement you'll find dirt roads that are more or less maintained. But even the really bad ones never turn suddenly into steep hill climbs, mud bogs or boulder fields.
So, no need to bring your buddies.
With good common sense and the safety of a cell phone (satellite phone for remote areas) you don't have to turn a Sunday drive into a multi-car expedition.
However, its fun to be with friends if they want to come along.
However, if you want extra safety - learn more about your 4WD.
However, if you want to tackle a really challenging trail - don't go alone!
However, if the area you are about to explore is extremely remote - don't go alone!.
