Our vehicles were rear-ended THREE TIMES in a period of about 18 months. We bought a dashcam from the "Kim Komando" radio show shop. It has two lenses - a wide angle that faces forward, and a narrower angle facing the rear. We've been using it religiously, whether in the RV, my truck, or the wife's SUV. It's easily moved from vehicle to vehicle. The model we have is no longer available, but there are plenty of dual-lens models available.
