The onstar hotspot will run continuously with the engine off, if the key is left in the ignition and left in the accessory position. It will however drain the battery.
To prevent the battery from being discharged, I have left the truck connected to the RV if I have shore power. This provides at least some recharge to the truck battery. I have also hooked a stand alone smart charger to the truck battery. From doing this it appears that the OnStar radio and other phantom draws when the ignition is on total 6.5 amps. Ihave run the hotspot for several hours this way. Since we mostly use the internet at night, the 160 watt portable solar panel is not an option.
I was hoping you might have some other alternatives.
