2010-2013 rust updates

hey guys. im in the market for a new truck. I have my eyes on a 2010 Tacoma with trd sport package. I know this question has been asked a million times, but I haven't found any solid info on 2010 and later tacos. Did Toyota fix the issues with frame rust?. I know this was more common on older models, but I did see a few instances on 2010 to 2013 models, and they were not in snow or salt water and were in the south. I will not be using the truck in snow, but I do launch my boat in saltwater on a regular basis. I know surface rust is not a concern structurally, but I still think there shouldn't be any rust on a frame that is less than 5 yrs old. I have an 04 titan with zero rust and ive been using it in salt water for 7 yrs. Anyone have 2010 or newer taco showing any signs of rust already?
