Anybody have any idea how much weight can be put on a 2004 f-150 tailgate? I have a motorcycle ramp and a 700 lb Harley plus me on top is 925 lbs on the gate. Is this a problem for the cables?

 

I guess ya could just try it and see what happens

 

I think the heaviest object I ever loaded in my truck with ramps was an upright piano.
I too was concerned about cable strength so, I just removed the tailgate, used the ramps on the bed and then put the tailgate back on.

Only takes a minute.

I have loaded a bike using the tailgate but it was only a 650, less than 500 lbs.
