Why did I go to a DOT officer, well I have worked with them for years, mainly on over the road trucks. No they would never normally inspect a RV unless it was a blatant visible violation. I could not get Keystone or the dealer to deal with the tires, now I can replace the tires and take them to court for the cost because I have a legal document (ticket) proving the tires should not have been put on that trailer. The tires are rated for 1500 pounds, the trailer gvw is 7700, do the math. I also have a equalizing hitch that transfers some of the tongue weight back on the trailer axles.
