Most definitely look for used ones, unless they've been badly abused or damaged. I recently ordered a Host Yukon for delivery in 6 months & then started looking for tie downs, turnbuckles, & spring Stableloads, all made by Torklift. I looked on eBay, Facebook Marketplace, Craigslist, etc. I found a set of the stainless tie downs & Stableloads from the same seller, who had only used them for 6 months. I found a set of 10 year old Fastgun turnbuckles with locks, that had been in storage for quite a while. I also found a rubber bed mat used. I saved well over $1,000 on all of it. I had the most luck finding stuff on Marketplace. It will take patience & time, but it's worth it.
