Does anyone know the load rating of the tailgate on a Dodge RAM heavyduty? I have a heavy Harley-Davidson (about 1000lbs with rider) and have been unable to find any specs from DC on the tailgate cable rating. I have seen cables break on older trucks. This could be a serious safety problem riding a bike up a ramp and having a tailgate drop!!! I know I can take the tailgate off and then run it up the ramps, but don't want to do this if I don't have to. Thanks
