In Texas "traveling" is accepted as "an overnight stay outside your resident county". It really ends up being a "don't ask-don't tell" kind of deal. I never understood the idea behind having a pistol in a vehicle if it is in one location and the ammo is in another. On top of that a shotgun is no problem. Just don't put it on top of the dash, looks to aggressive. That is one reason police dropped the Colt 45, to aggressive with cocked-and-locked and it scares the public.
A good location for a shotgun in an H3 would be in an over-head rack just inside the rear door. People rarely look up when they look inside a vehicle.
As for me, after 9-11, the FBI mandated all law enforcement officers will carry off-duty. I just had to get my shirts one size bigger to help conceal it.
