Hell, for no extra cost, my 2010 Hyundai Santa Fe has enough storage under the rear cargo area to carry a Mossberg 500 (pistol grip, 18.5" barrel), a 28" barrel and original stock for same, a Ruger 10/22 with scope in soft case, a Winchester model 94 (carbine in gun sock), an SKS with TAPCO stock (removed the adjustable stock part of it), several boxes of ammo, targets, and a Springfield XD 40 subcompact in original box. Granted, it was tight, but it all fit and the lid closed.
Unfortunately, I recently lost all these weapons in a freak boating accident...
