Pro Series Weight Distribution - PS49902 question!

My trailer is 31' and 3500 dry my pro series pulls it no problem, quality seems good and it is heavy. Yes its a pain to put on and take off the friction bars but its not difficult. I use both friction bars and grease up all the moving parts before a trip. I barley feel any big rigs passing me and tow at highway speeds without a problem. Those other hitches are nice to have but if cost is an issue this will work just fine.
