i have a 03 crew cab 3500 with a western hauler bed im wanting to put either 19.5 ir i really want 22.5 but i dont know how much i would have to lift my truck and i need the gooseneck and the last truck i saw with 22.5 the guy told me he could not pull a gooseneck please help! Pics would be great flat bed or not

 

I would stay with 19.5's. I think the 22.5's are too big. But that's just my opinion. A lot of tow trucks have 19.5's, so I bet you can get a set for a lot less than the 22.5's.
Good Luck

 

There is a member on here (DWIGGS) that is running the 22.5's on his truck, no lift. There are pics too,, if you do a search for "finally after 4 months" you should be able to see pics of it
