Winegard Roof

Have you located the power supply to the antenna dish?
Does the antenna make any noise?
Manual

thanks for that manual. It helps. Yes the power supply appears to be hooked up as the manual requests. When you want to watch your direct TV instead of the antenna how do you set the tv input? I cannot get the tv to recognize channel 3 or 4 at all. No view of direct tv menu on screen at all

I would try to get the Directv screen on the tv before worrying about the sat dish/satbox connection. You should get the Directv logo or the sales channel (100)? with no dish attached.

You mention connecting the dish to a receiver; do you mean sat box?

Are you sure dip switches are set to Directv?
Make sure the cable from the dish goes straight to the receiver.
Verify that the output from the receiver goes to the TV.
It should come up automatically to the DirectTV screen and input. If it does not then cabling is incorrect and goes through some device.
I have a video switch to change from different inputs. Cable, antenna and satelite

I cannot figure out how to get the direct tv screen on my tv at all. Bummer. Maybe I will have to take it in to camping world or some place. Good point about not worrying about the sat until I can see the direct tv portion.
I did verify the dip switches are set as per the manual sent above.

CW is the last place I would take it.

Instead of messing around with composite adapters, why not buy a $130 flat screen from Walmart and connect with HDMI.

Do you have the antenna power supply switch turned off?
I would call Winegard!

No does that matter?

Some of the antenna power supplies will allow satellite to pass through when they are in the off position.
If you did power the dish through the old antenna power supply, that could be your problem.

Let start fresh here. Before you have any concerns about the antenna on the roof you appear to not have a proper connection between the TV and the satellite receiver and that's what you are looking for help with.
Are you using an adapter to convert the Yellow, Red, White RCA cables from the DirecTV receiver to a coax output? I assume that this is the unit that requires you to use channel 3/4 on your TV. If so, this is also usually powered and needs to be plugged in. From that converter the first thing you want to do is run a new piece of coax directly to the back of the TV and do a new channel scan with everything connected and powered up. Be sure the TV is set to Antenna and NOT Cable before you scan and it will find analog channel 3 or 4. This will get you a good starting point.
Once you have the direct connections working you are going to need to work backward to make the necessary adjustments.
If you are trying to see this signal on multiple TV's in the RV then you should have some kind of a switch box with buttons labeled Ant, Cable, Aux, ect. If not then the coach may not be set for sharing and you are going to have to modify some wiring by adding an A/B switch but I need to know more about your setup. If you only need the satellite TV to show up on the TV where the receiver is located then just install an A/B switch that would allow you to select the current OTA/Cable option or push the switch and watch satellite TV.
