The Spot Trace I have mounted in trailer takes 4 aaas and I can buy a plug in cord to go strait to trailer battery. If trailer batt dies the aaas are back up. They come with a mounting bracket. As long as they are facing sky through wood fiberglass plastic. The last pic is the plug in to run off 12v battery. The trailer one I have active texts me that it is working and hasnt moved. It will text and or send email of location. If the battery is low it tells me.If it does move it will send me a google earth update every 5 min as it tracks. Forgot to turn it off and tracked me from Valmount home. I like the app for my android or apple that I can see my trailer wherever I am. If you have a fibreglass roof on the v nose it works great havent tried it under metal roof will give it a try tomorrow and let you know. https://www.youtube.com/watch?v=UJbCqFewves
checked tonight and the metal roof will block signal to spot. If it is placed in a roof vent or fibreglass nose it works fine. If you have an external battery box it would go through the plastic lid.
