I would like to install another radio in my vehicle as a backup and for packet operation in my Chevy Suburban.  Currently I have a 2M/70CM Radial Larsen NMO antenna mounted just above the Driver/Passenger area.  I need to mount the other antenna up on the roof but am unsure of where to put it.  I would like to keep the mid part of the roof open for a roof rack that I plan on getting down the road.  Is there any problem with mounting the other antenna on one of the back corners of the roof?  I say corner because it would leave the other back corner open for something else.

Where ever it will fit, but keep them as far apart as you can. You could even use the hood seam. Just remember, there will be de-sense in the opposite receiver.

Here is a bit more info on the gear that I am going to use.

Yaesu FT-8800R with Larsen NMO2/70B (Dual Band 1/2 Wave NMO Mount)

Yaesu FT-1802M with Larsen NMO-WB-150-BK (Wide Band VHF 5/8 Wave)

I mounted the second antenna yesterday and am waiting on the face plates from Gamber Johnson to install both radios properly.  The antennas are about 6+ feet apart sitting at opposite ends of my Suburban's roof.  When everything is done I will report back with any issues and also some pictures.
