we travel a lot on interstates on long trips. I’ve only had 1 blowout - driving too fast- and one flat in a parking lot from a nail. But finding a spare to replace the one I put on is almost impossible in the right size and load range. And I don’t wanna not have a spare. So I’m thinking of getting another but not sure where I’d keep it. Any suggestions? Wondering if there’s a way I could mount under the trailer somehow.
