gday chris
the 160 is from the high part of the chassis at the wheel location, the underside of the checkerplate to the low part of the chassis at the rear measures around 240.
the measurement between the top of the tyre to the checkerplate as around 250
ive got a steel tray so it doesnt need as many or as large rails as an aluminium one would.
im about 5 foot seven and when loadin gear in the back the tray sits at gut level, just about perfect.
hope this pic works, those last pics were monsters sorry bout that
.
cheers
steve.
