While a tailgate pads are cheap and do an ok job of transporting your bike, do not believe for a second that they will not damage your bike or vehicle.
I designed the MultiTaskR because of all the problems I had when I used a tailgate pad and all the other problems that Ive seen( bikes smashing together, bikes hopping when hitting a bump and the scuffing of paint on the tailgate, etc.) as a matter of fact, Ive had reps from 3 big manufacturers tell me, after seeing the MultiTaskR, that they had carbon frame failures directly connected to tailgate pads.
The MultiTaskR, while not in production quite yet( hopefully by Sea Otter) has been tested rigorously for over 18 months and the results have been outstanding.
I first designed the MultiTaskR to fit bikes, then using a mount we call the "MultiMount", it is able to carry just about everything that you would regularly carry inside your truck bed, such as ladders, surfboards, kayaks, lumber, etc.. We also have a behind the cab mount, that has a upper crossbar over the cab and a lower crossbar, expanding the opportunities of this rack.
The MultitaskR folds down in seconds and is completely removable in less than 30 seconds and every type mount has a lockable feature.
