The zuke's completely standard, so no winch, and I'll either be going solo, or with a friend who rides an enduro bike

So I'm looking for advice on what gear I should have incase I get stuck?
Currently thinking at least a hi-lift jack, a pair of small waffle boards and a shovel.
Anything else that is either necessary or potentially extremely useful?
Found this guy who looks to have a great range of stock;
