That's very good advice. I started carrying a spare spring after I replaced my original flattened out springs with American made which were not a bit better, and on a trip in June, (without the bike in garage) I had the left rear spring break completely apart, it let that tire come up and skid against the front tire. Happened on a busy interstate out in the countryside. My Good Sam Roadside Assistance got a service truck out there and the 2 of us changed out the spring with the spare alongside the interstate. I now have a new set of Lippert 4K 7 leaf springs installed and although I'm always skeptical they sure look good. We took the bike to Black Hills over the 4th of July, no more sag. I will still always carry a spare spring and recommend that anyone with a heavy 2 axle trailer toy hauler carry one too!
