rjxj: Thanks for your quick response. You bring up some very valid and important points. Never thought of leaks from day one, but that is very likely.
Re my gal: Yep, and that could be a reason why I have stayed married to her for 42 years ,so far. As a footnote, she is the one wanting a new trailer as I am content with the one we have. She is such a great partner and asks for so little, whenever she really wants something, I will go through heck on earth to get it for her.
Again thanks for your response.
