Okay got out to the RAPTOR today, still colder than He...l high little over 30 today. Like I said in a previous post I never had any issues with the straps/hooks I have been using (relative term). Easily hooked into the garage floor. I found a heavier strap than II have been using in the garage which had an attached hook material diameter of 15/32". Hooked it to the floor with no problem (loose). My guess it would take a .5" diameter hook (tight).
For those having problems not sure what size hook you are using? I do not remember the capacity of this larger strap?
Since some Raptor owners are having issues and others not, KS may have changed the depth or diameter of the cup welded to the frame. I am sure this would not surprise anyone.
