You should be able to lock onto either 110, 119, or 129 (western arc satellites). A couple of things to try:
1) Make sure the coach is level; if not, it can affect the elevation and azimuth settings.
2) Depending on the receiver, you should be able to go to Menu, select 6 (system setup), then 1 (installation), then 1 (point dish). Set the satellite to 119 (if that's the one you want), then make the dish search until you get a decent signal strength.
I'm stating this from memory, as I don't have my coach at the house. Also, I have a different brand of antenna (KVH Tracvision S2), which is very old and not really supported any longer, so I have to force a lot of manual searching to get the satellite I want. I apologize if this isn't helpful.
