Nitro express,
I have had Truck Vaults in a 94 Bronco, a 2000 Tahoe, and a 2010 Expedition, and I would not be without one. I think for a "SUV" you will probably find the single drawer most useful because you may discover that your gun case would not fit into the two drawer configuration. You may also want to consider getting the diagonal divider option which I liked since I generally kept my hunting guns assembled vs. broken down like I travel with my trap gun in a hard case. Once hunting season begins I Switch from trap mode with dividers out to hunting mode with dividers in. If you have any further questions feel free to ask.
