Tom, you apparently do not have 44" inches of travel in the lower front area, so if I were you, I would install it at the very front of the raised roof area. When collapsed, the 3005 should not be higher than 10" which is much less that the dome. Also, I suggest you use the aluminum plate which helps spread the load, but be aware that it may have to be offset a little to properly align the dish. As to the wiring, your existing two signal cables will work, but there is a new control cable that has to be install in the coach ahead of the receiver and that cable cannot be spliced. A new hole was drilled to handle this cable and the package of cables was enclosed in a plastic wire protector and clued to the roof. If you would like, I can set up a ladder and take some photos.
