We have the Trav'ler on our trailer and love it. We have a X2 in the garage, somebody make me an offer.
What it really means for a trailer to be prepped is they ran the control wire and TV cables from somewhere inside the trailer to someplace on the roof. They work with all the different satellite companies.
The Trav'ler is built for 3 different satellite companies. It's really 3 things;
1. a control box that is programed for the specific sat company
2. a multi-axis pointing motor
3. a sat co specific dish/horn.

We got on Cedar Creeks website and found the drawing for it.
For some weird reason the control box goes into the bedroom closet. There was a 110 outlet and a blank switch plate. I took off the switch plate and my wife stuck her little hand up there and found the control cable, then over by the TV we found the color coded coax cable.
Up top there was a sticker on the roof which said all the stuff was under here. I cut away the roof membrane and found the other end of the control cable and 2 color coded coax cables w/o ends.
The hardest part was hauling the Trav'ler up on the roof.
Then I found a good place for it and really, really, really took my time here. Lots of Dicor and then screwed it down by hand (I wanted to feel when the screws were getting tight) then a lot more dicor.
Ran the wires added the coax ends and cover, secured the cables and a lot more dicor.
Plugged it in, turned it on and watched it dance and badabing it locked into the 3 dish satellites. We hooked up the cable to the 211Z and reprogramed it per instructions and it is flawless.
Just be sure to get the Trav'ler that works with your satellite company.
