Yes, my rig has the Arctic Insulaton, so I expect it has the roof insulation, and yes, I am looking at the wireless units. Don't care to put more screws into the outside walls, but that seems the only way to get sufficient radio wave reception. Looks like maybe the Haloview will work. I like that it comes with the option of a signal repeater and that apparently the infrared lights (not sure how they work) apparently won't blind following drivers should I use it while on the road, as well as for backup. The helpfulness of this forum reduces some of the inevitable trial and error portion of RVing and for that I am grateful.
