Agree. We have decades of off-road Jeeping experience, so are NO strangers to tire plugging to get back to home/back to the road. We carry (and use) heavy duty, all metal (not metal/plastic) plug kits in all our vehicles.
Be aware that recent developments in the tire business (now) will likely/may preclude a corporate-owned tire shop from patching a previously plugged tire, due to today's excessive/overly litigious (law suit) environment. They will say "plugging enlarges the original hole".
Many family owned shops, out of legal caution, will (now) also decline to patch previously plugged tires. 🙄
Note: The location of the hole/plug also is a factor - anything in the sidewall-to tread area transition point ("shoulder") is a "no patch" area, however if you have to get to a tire shop/home, an old-school plug will get you there, even if you have to subsequently replace the tire.
Often it's faster to plug a tire than change it. Another consideration is - the less time you spend on the side of a the highway, the safer you are, due to "distracted drivers" who don't yield to LEO/safety vehicles, or disabled vehicles on the shoulder.
Also some tires have internal surface contours/coatings not conducive to patching, which could also cause a tire shop to decline a patching request, so don't be surprised at that.
Good luck, and be sure to monitor/check your tire pressures regularly.
