Ok guys im about to start pulling a 27 foot 5th wheel camper with my 2010 CM SR5. I want to put in a gooseneck ball instead of a slider hitch since i will be hauling horse trailer etc. Now my question is has anybody done this? What kind of extenders etc. do i need to use. My 5th wheel has a gooseneck adapter on it already. And what kind of airbags are best used with my truck? Im running the 3/1 rough country leveling kit. Thanks guys for all your help!!!
