Where to place GPS and XM antenna

We just bought a 2009 Mandalay 43A. I'd like to install an in-dash AM/FM/XM/CD Navigation unit; something like the AVIC series from Pioneer. My question is this: What's the best way to mount the two antennas? There's one for the GPS and another for XM. I believe the roof of the coach is fiberglass, so a magnetic mount won't work.

Please don't tell me to just use a separate GPS unit. I have a Garmin that I'll use until I install the new deck. I prefer the in-dash navigation to the sit-on-the-dashboard variety - Personal preference.

Thanks in advance,
