Thinking of trading the '03 GMC 3500 for a 2014 GMC 2500 standard bed (6 1/2 ft.) Will my 16K fixed hitch work with the '05 Cougar 309EFS or would this setup require a slider?
If you are making turns going forward or backing that would make the fiver hit the back of your truck you are putting way too much stress on your fiver's suspension. You can turn it into a real twisted mess! Find another way to do what you are wanting to do. A slider will not prevent it.
