Been there done that. If I were to do it again, I would carry a full sized spare that matches the others on the vehicle and also a GOOD tire plug kit. Don't get the cheapies that are for temporary use. Wish I could remember the name of the one I bought but mine has a metal tip for insertion, does not require any vulcanizing material and is considered a permanent fix. If you're not comfortable that it is a permanent repair, it will at least get you a very long distance to a repair shop. Oh also, get a good 12v compressor to air your tires back up. One the best is sold by Viair. Plugging the tire allows you to do a quick and easy repair without having to remove the flat tire and mount the spare.
When we were in Alaska, there were places out in the sticks that you wouldn't want to be in the process of changing a tire and have some critter pay you a visit.Good luck have fun!
