One of the "advertised features" of the In-Command system is "global control". ASA advertises it this way: "Global Connect™ allows you to control select functions of your RV from anywhere in the world using a smart device with a Wi-Fi or cellular data connection." So, being 30 miles away, under the correct conditions, would be a "piece of cake in butt dialing"....
The "TRAILER WARRANTY" (from Keystone) is 1 year. Many (most) of the individual components in the trailer carry a longer warranty from the "component manufacturer" (not Keystone). During the first year, Keystone will "arbitrate the warranty on components) so the process "seems seamless to the customer". After that first year, it is up to the dealer/owner to arbitrate the remaining component warranty. ASA has an extensive website to "educate" users of the In-Command system.

I'd urge you not to consider your In-Command system to be "out of warranty" until you can confirm that with ASA.
I'd suspect that most RV dealerships are "struggling with issues as the In-Command system comes online. Most RV service centers have one, maybe two techs that know much about the system and the rest of the techs "more or less" struggle to change out components with little knowledge of what they're doing. It's not the dealer's "fault", rather it's a new, highly complex system that few understand, fewer have training to support and even fewer are experienced in repairing the system.
More and more trailers are being produced with the system and GM is now "onboard, installing software to support In-Command" in their new trucks/SUV's designed for heavy towing. So, it's here to stay (at least for the foreseeable future) and ASA wants to make the system work so they can sell more of them.... That means they're working with owners to keep them happy, the last thing ASA wants is a lot of negative comments that cause buyers to not want the system. So, check out the website, contact ASA, see what they say. They've supported lots of owners "out of warranty" to keep the "growing pains" simmering rather than boiling.....
