We’ve often travelled alone over the years - I’ve often carried a Tirfor, shackles, star pickets and short sections of chain to hook them together.
A long handled shovel and a short spade, plus a snatch strap and strap extension are always in the kit.
The Tirfor is a peace of mind back up, but it’s hard work using it, especially with a star picket ground anchor, so it makes you cautious about where you go..
Sometimes turning back and driving a four hour detour is the quicker option.
