That's what I do. Dealer usually has a lift too.

One of the common problems is the bike hanging up on the area between the ramp, and the tailgate as the bike goes up the ramp. You could park the truck in a gulley with the nose higher than the tailgate. This would lower the ramp angle and avoid the hangup.

I use my Harbor Freight aluminum tri-fold ATV ramp. Works great but I usually put the back tires of the truck in a little depression to flatten out the angle some.

Here's what I have. I've used it for various bikes. The arch eliminates any dragging as the bike enters the truck bed. Very light but durable. Using center piece alone handles 1500 pounds. All three linked together handle 2700 pounds.

I think I'll probably go with the Black Widow ramp. Looks pretty useful - about a 9 foot length.

Just don't think I'd want to load my bike in a PU truck with ramps.. Just me...

Maybe with some kind of loading dock, that'd be a lot safer.

I just picked up a set of Black Widow ramps. I haven't used them yet, but they seem to be extremely well built. Fast shipping from discount ramps too.

I have something very similar, could be the same brand but I'm not sure I bought it at a local trailer supply a long time ago. I also have one of those narrow ones that fold in half and I wouldn't recommend it for anything bigger than a dirt bike. I usually tie it off to the truck or trailer so it cannot kick out when you pass the top, I've had them kick out in the past so I learned the hard way.

Another happy Black Widow ramp owner. I have used them for my sportster but not for the softail yet. Yes they are pricey but it's one of those things where you dont want to be cheap.

The 9 footer? It shows discontinued right now. :(
