Just like Charmin Facial Tissues don't want to be called "Kleenex", name recognition is important in any business, so important, in fact, that Tom actually had to pay money in order to use the name "Trillium" on his trailers. As enthusiasts of this special type of product, I think it behooves us to use the correct, legal name.
Actually, I have had experience in calling things by their correct name. One of my tasks in my former job as an engineering technician was to write instructions how to use the tools we designed based on the testing instructions in engineering documents. I found it very difficult to understand what was being said when the name of a component became names, eg hydraulic cylinders were at various times called actuators and other things. It was difficult to write instructions not knowing just what was being said in a document. So I am more sensitive to such things than the average bear.
I also know how easy it is to slip into various name usage, for I have done it myself many times. I had to always review what I wrote to weed out these types of errors. I know just what you are thinking, "Oh God, not another engineer on the website!"
Thanks for an interesting discussion.
