Review on 📱 High-Quality 2-Pack TT&C Magnetic Car Zinc Alloy Phone Mount with Upgrade Magnet 8pcs - Universal Dashboard Holder, Cell Phone Grip Car Kits, 360° Adjustable Super Strong Magnet for Samsung, iPhone, LG (Black) by Joseph Reed

Place this in the trailer so your hands are free but the screen is visible. The magnets hold the phone well in the truck. Update: The handle holding the magnet broke off the retractable arm. I glued it with super glue but to no avail. The grip has come loose again. The ball mount is not strong enough for commercial use. The vibration of the pendant and the weight of the phone are too big for the grip. The magnet does its job very well. Would not recommend for commercial use.
