Modern skinny spare for older mopars

I personally do not have a lot of faith in fix a flat, but have been using trucker style plug strips with a container of Slime on board as an emergency back-up for years. Trucker strips have never failed to repair a screw or nail on the road. Even bailed out a motorcycle rider near the Arctic Circle in Alaska
I never heard of a "truck" style plug strip but since you mentioned it, I did a search and sure enough it comes up. The pictures however look the same as what I have purchased for the past 30 years for my cars. Is there a difference in diameter or length? Maybe it is just marketing? But I agree either way, those plugs are awesome. I once plugged tires for practically every neighbor when our subdivision was under construction in the late 80's...nails everywhere back then. Seldom had a case where the chords were damaged and a repair was impossible.
