I have one of the 1 foot wide ramps and I have no problem loading it. My truck is lifted a little, so I would assume your avalanche wouldn't be any taller. I paid somewhere around the price range that you are looking at. But if you aren't my size, 6'2" and 205lbs, your experience might be different.
The only time that I had an issue with the ramp was with my buddy's 600 when the lowering link broke and it was sitting all the way on the ground. But all i did was pick the bike up once it got to the point it hit and push it into the truck. granted, I had help in this instance. His bike is lowered 2" and rolls in just fine when it's not broken.
Hope that helps.
