Being an engineer, I was thinking about building something to eliminate this problem, then decided to search the Internet, first. Low and behold, there is BOWDUPLOADERS. Mine arrived two days after ordering, and I just finished the installation. I am VERY GLAD I opted to purchase this rather than build it; it is beautifully designed, engineered, constructed, and finished with a really nice powder coat. And, it fit the bed of my Viking LIKE A GLOVE. In fact, my bed was spray lined when the machine was new, and that made the fit even tighter; I had to use a rawhide mallet to “encourage” it into place. It fit so tight, I am not even sure I needed to install the mounting bolts! I HIGHLY recommend this fine piece of equipment; especially if you hunt by yourself, or are getting on in your years, like me. An injured back just isn’t worth it! Drop Arty a line, and see about getting your copy, today; you will not regret it, and your back with thank you!
