I bought a 1999 fleetwood and it came with a set of turnbuckles. My truck has frame mounted tie-downs and had to use chains to make the old turnbuckles fit. Also during a few of my trips I felt alot...
I've been using chain extensions for years and even they might be a bit annoying, new fastguns come with sticker shock. Are you having old 2 turnbuckles spring-loaded?
