It has helped me keep inventory of my trailers to make sure I am not missing any items in them that need repainting etc! We have been able use it during storms when there are power outages so we could track our vehicles without having constant access via cellular service because if you run into bad weather your phone can be ruined too :) sometimes takes awhile at first but once its set up all will work well with no problems. Tracking vehicle mileage ect would help get better prices from customers who dont pay their bills early enough due to being caught off guard about payment dates.
