Also, I have an '06 with the stock water heater. Is that a problem?

What brand are these bags you're talking about?

They're actually Silverado bags. They're a pain to mount. Having said that, there are bags which are very similar, almost exactly the same, on E-Bay for about 300 bucks. Those wouldn't be hard to mount at all, because they have a flat inside wall (mine was indented for Silverado fender stays, so I had to deal with that). You would just replace the fender stay bolts with Easy bracket bolts (5 minutes), and then bolt the easy bracket plates to the saddlebags. That would probably take an hour or so because you have to measure very carefully. But once you have them marked how you want them, then it's just a few minutes to drill out the holes then bolt them up. Then you're done. All you do is put them on the fender bolts, turn the key, and you're done. Easy brackets are about 135 bucks. So it would cost you about 435 bucks to get it all set up. Hope this helps

In my mods album are some pictures from the top which show the easy brackets...
