My truck gun for the last few years has been a Marlin Papoose.
It's out of sight, doesn't resemble a rifle at all, and you kinda have to know where it is or it just "isn't there." This "truck" is an SUV and has a lift panel in the back where jumper cables, tow straps, first aid kit, and so on live. As well as a brick of .22LR and spare mags.
This has nothing to do with zombies, saving the world, acting as a counter-sniper, or any similar drama. It has everything to do with emergencies of the kind often encountered in places like the Inland Northwest (North Idaho, for example). Up there it's really pretty easy to find yourself out in the woods, well away from the main roads, and driving on some poorly maintained (if at all) dirt road with axel-deep ruts, or in fresh mud or snow.
You get stuck out in a place like that, you will want to have options, and a light rifle with way too much ammo is a "good thing" in the Boy Scout sense of the term.
In this same truck is a "truck box" containing blankets, water, food, knives, an axe, a short machete, another first aid kit, and an assortment of handy things to have ... just because.
The rifle is just one more piece of that kit. It's legal pretty much everywhere, I don't need a permit for it, and if I have to hike, it's light and compact.
So, yes, I am in favor of a truck gun, properly stowed, discreetly, against the day you find yourself engaged in involuntary camping out in the boonies somewhere.
In civilization? I'd have to get kind of creative to come up with a plausible "survival" scenario that involves the rifle. Who knows? Maybe I should try my hand at fiction.
