I have the same truck. I have seen the auto-loaders, and talked to the owner....he liked it and hasn't had any complaints. I weighed this purchase in my mind as well...but I was reluctant to drill holes in the bed of my truck. I have a "Toy Hauler" ...but mine was possibly only a one or two time move ( I moved my Ultra from Cincinnati, to L.A. for the winter and was not bringing the camper). I did not think I would be needing this loader very often. ...so I googled " motorcycle hauling in the back of a pick-up truck" and came up with a great idea...for lot less money. A 3/4" piece of ply wood, with handles(for ease of handling/loading, Pingel wheel chock installed, 4 tie down rings installed in it. I borrowed a wide loading ramp( for a 4 wheeler) from a friend. The Silverado tail-gate sits very high....so with the aid of a ditch...or a hill....or a loading dock somwhere....riding up and down the ramp was no problem. BE SURE to secure the ramps to the back of the truck somehow....I used a tie-down strap to the trailer hitch.
I tied the bike down to the 4 installed ring in the plywood and to the two front tie-down rings in the front of the bed sides....securing everything in the bed ( 6 tie-downs total). The plywood supports the weight of the motrorcycle on the tailgate of the truck. The rear wheel rest right about where the tailgate pivots.
Probably too much information...but it worked out great for me.....GOOD LUCK and I hoped this helped.
