Thanks for the responses.
The braking system is a Blue Ox Patriot 3.
It was set up by an RV repair place here in town. Everything is very "clean" regarding the way they put it in. We will be setting it up for the first time today as we leave Sunday afternoon.
The tech suggested locking pins for the tow bar where it hooks into the RV. Sounds logical, I am trying to locate the right size ect.
I will cut off water at the street as the house shut off is a 35 foot belly crawl under the house. I haven't had to crawl for about 8 years since I quit drinking.
I just want to say that "you people" and RVers in general are amazingly helpful. I visit many forums, as I am a hobbyist musician and studio owner as well as a full time Physical Therapist, and there is alway a few who want to use the forum to elevate themselves, talk down to newbies and pontificate. No so here.
As they say, we all didn't know the answer at some point.
Much thanks for taking the time.
