Howdy!
Have you considered using a Reece Goose Box? When I purchase our new 3500 DRW Chevorlet recently I decided now to go back to using a 5er hitch. I purchased a Reece Goose Box 20,000 lb pin box and use the goose neck ball on the truck. I really like not having to deal with the 5er hitch and now having a clean truck bed if needed. The goose neck ball is easily removed compared to the 5er hitch. We fulltime and the Goose Box makes for a smooth comfortable ride with the shocks and airbags within it.
