Review on 🚗 EWAY WiFi Wireless Magnetic Trailer Hitch Backup Camera & 4.3 inch LCD Monitor - Safety Solution for Gooseneck Horse Boat Travel Trailer/Fifth Wheels/RV/Camper Car - Removable Guideline by Adam Johnson

Dyno test shows product works. Video quality and responsiveness were fine. However, after putting it on the bumper of a 19ft trailer, I couldn't get a stable chuck. It wasn't possible to use the rear camera due to the lag (I was much further away than the camera indicated - and the lag was around 1-2 seconds!). I've tried different mounting locations (top, left, right, etc.) and moved the receiver around the cockpit to no avail. This may work for shorter distances but will not work for RVs longer than 19ft.
