And if this trailer is going to end up on an aircraft the dataplate should be accurate!Aircraft regulations are much, much more stringent than trailer regulations.
I don't remember reading where anyone called your bedliner shoddy?
My question, now that you have resolved the scale accuracy part, Do the wheels have the heavy run-flats in them? The wheels could have been swapped at any motorpool with wheels with run-flats.
I haven't removed the wheels to weigh them, however from talking to a SNCO friend of mine in the Army he said that all the wheels are built the same since they could end up on a HMMWV or this trailer. I'd assume the runflats would be installed, and that they'd be inlcuded from the factory.
So, is it common practice to build the 16.5" two piece wheels with Goodyear MT 37" x 12.5" x 16.5" wheels WITHOUT runflats installed, for trailer use?
