This Arkon SM678 has a slightly larger mounting base with more contact area than the Arkon SM679, making it slightly better suited for heavy equipment on rough roads . We use ours with a 7 inch tablet that we use with an OBD2 app and a bluetooth OBD2 reader for additional engine sensors. We do a lot of bumpy forest trails as well as many 3-8 hour freeway drives and only had a suction cup once after sitting with a tablet in the extreme heat over the weekend. This was after a few months of operation and nearly 2000 miles. I use the included 3M mounting washer as my dashboard is soft to the touch (soft) with a highly textured finish.
