Real towing advise please

So many people try to tow with the bare minimum. RV haulers use real trucks and real hitches the kind that eliminate sway. Don't go cheap when your life depends on it. I have towed trailers and fifth wheels and the biggest problem I had was with finding tires for the back of the truck that would handle the tongue weight of a big fifth wheel trailer. Then again if I would have paid attention to the haulers I would have owned a truck with dual rear wheels. Good hitches like a Pullright hitch aren't cheap but they work when you need them.
