Why Truck Camper need a air bag? Do I really need it?

$2200 bucks is a little steep, I agree.

Still, to install the Lance plug is about $250-300, all the tiedowns from Torqlift are ~500, the Fastguns are $500ish depending on where you get them.

That leaves the airbag system at $1000...ish..

But then again, the airbags should not be necessary on a dually.
