I'm concerned that the cable holding the tailgate is strong enough to hold me and 800+ lb bike and the ramp. Can this be used with the tailgate removed?

 

We have loaded up full dresser Harleys with no issues on the tailgate. We have also loaded up many different side by side vehicles which also had no issues with. A lot of the load of the bike is transferred into the ground when riding up because of the positive arch to the ramp. I will attach a pic of a side by side being loaded up. The Shark Kage could be mounted to the bed itself without the tailgate but You would limit a lot of the features that way by not being able to fold it into certain configurations.

 

There are lots of small fabrication shops here in the US that would love to have that work.
