Success in getting cable reception!!!!!It goes as follows....and yep it was simple.
I started a movie playing in a dvd in the house....
Ran coax from out on dvd to cable in receptical on outside of trailer......
Did
NOT turn genesis system on.....
Toshiba input to air/cable,select cable....[this is buried deep in the menu]
Turned the Tv boost
OFF
Ran thru the channels,and presto the movie showed up on channel 3.....
The picture in the trailer could have been better,but I had to run 2 long coax cables.
I hope this helps someone down the way figure this out.Many thanks to all that have contributed to finding the solution to this problem.
If anyone needs anymore info as to what I did......just give me a holler.
