If your's in an '03, then most likey the answer will be yes.
If you've got the standard relocation bracket like Jared, it probably looks like this:
And since they changed the mirrors a slight bit for the 03's and up they stick out a lot farther, it's not going to happen. The snorkel sits flush right up against the side of the body and hinges.
So close in fact, that when you take your doors on and off, you'll have to loosen the two bolts that secure the snorkle to the windshield frame.
The only other option I could think of if you absolutely had to run the mirror on that side (our guys just tke them off with the doors), you could get the kind that you insert through your empty door hinge.
BTW:
Sorry, I just saw part of the snorkel instal page was broken. Make sure you check out the part I added where we installed a snork in Jared's '03. There was an extra cutting step that wasn't mentioned:
