Joe, your unit is DEFINATELY prewired, especially if you have that hook up in your cabinet. I have the same trailer, I had DRV install my Winegard. According to the tech it went easy. I know it sure didn't take long at all.
The wiring will be under one of those fake vents. I know when I put my solar panels up on the roof I had to use a piece of stout wire to "fish" for the pre-exsisting wiring for that. Took me a while but I found it.
Good luck getting that Winegard up on your roof buddy, they're heavy. That was my "excuse" to have DRV install it for me.
