The cable may stretch a little after initial instal and have to be adjusted. The adjustment is easy. You loosen two nuts and pull a little cable through to tighten it.
I had to adjust my hitch once or twice during the first year. I think that was just being over cautious to be honest.
I have not adjusted it since then (two years). We went cross country this summer towing a Wrangler 4-door that is just under our motorhome's tow rating. The Ready Brute Elite performed great and didn't need any adjustment.
