Hi Doc - we’ve been corresponding on IRV2 also. I’m starting to feel like the Ranger options are better and more expandable than the Wineguard. Would appreciate your recommendations on same. You seem to be the most knowledgeable person I’ve found on all of these boards. Maybe I don’t need a roof top unit...but it does instinctively seem like a good idea. However roof top means harder wiring and harder to change or upgrade. Any thoughts? I can see us wanting to use IPAD wireless, maybe a brick wireless and then any local WiFi depending on where we are. I have a bit to learn on how to manage the load balancing. Thanks
