I have always wanted to park my crewcab truck in the garage with my bike loaded on the dual rail carrier but the it was just too long to fit. Also, the dual carrier had ground clearance problems and it weighed a TON. I got tired of lugging my dual rail carrier out of the garage and I decided to buy this carrier. its very over built and rugged. It is a little pricey but you get what you pay for in the beginning.
Here is the company assembly video.

The instructions were very straight forward and the assembly was easy. I got the optional foot rest which stabilizes everything when placing the bike on the carrier.
Here is the gasser loaded in the down position with the foot extended.
This is the "up" position, no more ground clearance problems.
