Review on Frostory Car Reverse Backup Parking Sensor Radar System - Waterproof Sensors, Detection Distance: 30~150CM, Buzzer Beeps - 4 Packs X60D (Silver) by Michael Caste

Installed on a 2001 Dodge Class B motorhome with vintage chrome steel bumper. The kit arrived on time, with all the components, deserved the first time. I didn't want to drill into the bumper so I had to get creative with the installation. Good thing I'm a curmudgeon and a curmudgeon - found the perfect plastic sensor holder. The speaker cable is only about 15 feet long. Had to place the speaker about halfway in the camper. My RV is old and noisy when driving. I would like the speaker cable to be longer or the speaker to have more volume. The photo below on the bumper shows red sensors in a black frame.
