Ron,
Please don't be astounded by anything I say. I'm just a guy who comes to the forum to get advice and I try to reciprocate from time to time by giving some. I meant no disrespect to you, sorry if you took it that way.
I am on the "other side" in construction. I do not have the technical background to analyze and design things but I am very interested in it and I believe I have the ability to follow along. Most of my knowledge is based on trial and error without the math analysis. That is probably why I bounce back and forth between variables within the same paragraph. I also don't have the desire to ponder over the perfect words so that they can't be twisted to mean something I did not intend to say. For instance above, all I meant was usually a factor of safety is used as in sometimes there is not one. I actually don't know what you twisted it into other than saying there is no such thing as usually when determining a factor of safety or something to that effect.
That being said, the only intent of my post was to make people aware that specific to RVing, the variables in the analysis can be under constant change, and nothing more.
My last paragraph was meant to be a joke. Sorry you didn't get it.
