Actually, Federal law Title 18 USC, Ch. 44, para. 926A trumps all other state and local laws with respect to transporting a firearm. That Federal law allows unimpeded transport of an unloaded firearm for any lawful purpose from one place of lawful possession to another such place, provided it's stashed in the automobile trunk, or otherwise inaccessible from the passenger compartment.
So---No Trunk? Like an SUV?? Then you Gotta lock it up in a closed case, unloaded, with ammo and firearm stored separately. Otherwise, some LEO will tell the prosecutor that the full magazine laying next to the empty firearm constitutes a loaded firearm. And the judge might just believe it.
And further, in-transit storage is definitely NOT allowed by means of the glove box. [A specific line-item No-No.]
Now--that particular Federal law should allow anyone not living in Omaha, but just passing through, to effect passage unimpeded.
Provided...............A Whole Bunch of Other Stuff:
>What's the purpose for transporting the firearm?? To deliver it for sale in a non-contiguous state?? Oops! Requires FFL transfer. Not legal.
>Suppose an official considers your storage unit to be a "glove box". After all, you could put gloves in there. There's room. Behind the pistol.
>So--you say you put the firearm in the console, not the glove box. Too bad. Console = Glove Box.
>Must that firearm be registered in the location from whence departed?? Like some gun-hating city in Illinois?? Was it?? Uh-oh!!!
>Was ownership of the firearm illegal from the place you left?? Or the place you're going?? Gotcha!!
>And on and on and on. Sometimes a guy wonders how many firearms laws he's breaking at all levels, just by quietly sitting there, admiring his guns.
