Suits Tuff Trek mk3 and any probably other Roof top tent with North south M8 Fitting rails on the roof. (The Bush Company, Boss Rt1 etc) 
Allows placement of the Max trax at the rear where you can step up and get them daily for vehicle levelling or recovery.
Our Kit is basically the mounting frame,  Mounting of your recover trax to our Frame Requires your choice of mounts to hold the trax in place...
 
A Good example is the TRED PRO mount kit if your using Max trax or other brands of recovery trax with similar mount pattern, the TRED PRO mounts gives our base bracket  kit the 'PINS' for locking down the trax etc.
