That annoying parking assist alarm...
My new truck came with ultrasonic backup parking assist, and the "collision" alarm sounds when the camper is mounted and I shift to reverse. Not a new problem, saw complaints on a forum somewhere last year but just smiled as it didn't apply...
Got *real* tired of the noise-- no way to turn off sensors other than once per key cycle. So, I made some sensor caps from 3/8 PVC trim board, a PVC vent cap, and some rare earth magnets. Got lots of bumper space on my F350 dually-- these are 3.5 inches OD. All the plastic is solvent welded, mags are a press fit to flush with T-88 epoxy underneath. Inner ring is a snug fit over the sensor so there's no sliding on bumps. Central foam is a piece of 3/4 packing foam. Foam plus compliant cap absorb the ultrasonic-- no more noise when I shift to reverse. They work nicely around town, not yet tested on long road trip, but a strip of Gorilla tape is Plan B to ensure they don't go missing. Made two spares just in case.
