You've just answered a question I was embarrassed to ask !!

I bought one of those several years ago and never tried it..it looked to
cheap to effectively do anything. I think the last time I looked, it was
somewhere in the area of where I keep A/C stuff, which is under the trailer
wiring stuff I think, which is right under the last box of crap from my
long gone and forgotten Airstream....

Thanks
