IdaD, you're not going to explain common sense and technical properties to those that refuse to listen. In fact I likened a recent response to something my 9 year old with no filter would say, as some of the "information" here is almost infantile.
I've never seen a door sticker pull or haul anything yet, but then again at 44 years old I probably don't have the experience of some of our esteemed members.......
On the flip side I do understand things mechanical and it's just hard to get me to believe that an axle that is rated at 10000lbs in one application is overloaded at 2/3 that weight in another. (Of course someone will come along and give me a 2nd grade education on tire and rim capacities)
