Basically what Ubiety say's, will cover the. very basics. That kinetic rope is a better option over a recovery strap. It has the ability for multiple 'pulls' vs a couple from the strap (looses it's stretch). Prices have come way down on some basic offerings (Chinese). When your ready for some upgrades, a couple of soft shackles and a couple of steel clevis' types, in case of sharp attachment points on your undercarriage.
X=Bull recovery boards will do you fine and save you a bunch of money if getting stuck is a rare probability for you. Shop around as prices vary. Places like Amazon are a good place to research products from actual users who will point out the pros and cons of the equipment. Being in the desert, trees are rare, so for me boards get the nod. The ground in many places is like concrete, so shovelling would be a last resort.
If you have a trailer hitch, get a receiver 'stinger' . Sometimes it is easier to extract and recover backwards rather than forwards. I basically have the same issue posted above....."If I did not already have a tow strap I would spend the extra coin on a kinetic rope for that purpose". This is my plan also, as I stated, prices have come down quite a bit and I plan to fix this hole in my gear soon,
What Gunrunner Actual says is good advise. If you carry a more complete kit, your options open up. This is especially true if running solo, and waiting for someone to be driving by.
