I have laned lots of times on my own and always carry equipment to be able to recover myself, waffle boards (worth there weight in gold & invaluble) hi-lift jack, shovel, 10m tow strap, 4m tow strap, D shackles, the waffle boards are excellent at getting you unstuck and will free you in seconds most of the time, hi lift jack can be used to lift the vehicle or wheel out of ruts, ditches etc packing rocks etc under wheels in stages to get out and also can be used with straps & shackles to winch yourself just that little bit to be able to get traction again, shovel, well self explanatory, but I never entered terrain where I would run the risk of getting into difficuties when I am on my own, always walk the route a little if it looks if'y, take wellies and a stick for water crossings, so you can carefully walk the route and take a depth with the stick at the deepest point and compare it next to your vehicle.
But realy if you are new to laning dont bother on your own you could end up in big trouible and run a high risk of damaging your vehicle and maybe injuring yourself!
