Which View Mode for Panning Large Environment

IceScribe

Purchased the Harpwood Trail by HowieFarkes. I'm using the view port in 'texture shaded". Is there a betterr view mode that will let me move around faster in the environment? 

What I am trying to do is get a view on the trail to place a vehicle, but it is very slow going, and often the environment turns upside down. I am using a Microsoft mouse, which is usually reliable for positioning camera and props.

The way I moved around the environment was I put the environment in a group I called "Environment" and then moved that around translating on the (x, y, z) axis, mostly x & z and rotated on (x, y, z) but for that I rotated on y leaving x & z alone.
