Mobile LiDAR

We are in the market for LiDAR scanners across terrestrial, mobile and aerial platforms. I had signed up here with the hope of reading on user experiences. Given the cost involved, I would be happy for any guidance primarily from the practical side, in terms of data collection.

For e.g., with the mobile LiDAR is there a way to ensure 100 km of road length to be surveyed in a day, given that my DGPS base can "talk" to the Rover for only up to 15km. Does this mean that I do LiDAR survey for 15 km, come back and move my DGPS base/rover and do the next 15 (30 if you put the base in the middle)? Or is there is a technology that can let me drive the entire 100 km without having to change base every 30km?
