I watched the Endless RV video highlighting the tracker. I purchased the one with the extended battery life and installed it in my new RV. It worked great. Recently, the RV was at the dealer, and I could see every time they moved the rig. I called customer service with a couple questions. They answered the phone promptly and answered all my questions. I'm looking forward to the confidence I will have always knowing where my rig is located, since it will be stored away from my home. Amazing product and service at a very affordable price.
