yes, neither manufacturer makes these type of questions easily answered in any of their manuals - and the selling dealer usually does not have a clue either...
why they provide 'sat ready' wiring and base plates and don't tell the buying customer anything about it or the location is a mystery.... maybe we should go to work for one or both of them and let them know what it's like in the 'real world' when you are RVing and can't find this info in your 'Owner Manual', which many times is fairly useless..
I purchased a KingTailgater2 portable and have it 'temporarily' mounted on the rear of the roof near the ladder. It usually gets great reception of the satellite from there, but I have extra cable run around the rear AC unit so that I can move it somewhere else on the roof if needed, or down to the ground. I simple ran the two coax cables down the ladder, thru the radiator area, under the driver side and over/within the rear wheel well and up into the wet bay thru a floor cable hatch I easily installed. These two cables connect to two coax's that run into the coach thru the wet bay existing cable entry area at the top left... under the kitchen sink area, and both to the front living room tv(receiver), and the rear bedroom tv(receiver).
travel and enjoy!
