"The rub in this thread has centered around money... I mentioned the money bit in my OP because I'm wading through an endless list of things that need to be purchased before we start taking our TT on the road. When I ask questions on the basis of price I prefer answers from those who have no financial stake in my decision. "

I think from reading your OP money was emphasized as the major reason for the question. I also think the responses were appropriate and no one here could possibly have a financial stake like they would at a dealership or supply store. You are doing the prudent thing by asking questions and conducting research. Good luck on your new ventures.
