Air Bags/Springs - Firestone, Air Lift or?

Boatycall, I have upper Stable Loads. As I posted, I want to return to non-loaded height for headlight adjustment and level the TC when camping. Although the Stable Loads reduce the drop, I do not see how you could possibly raise the truck back up once loaded other than with air bags. I only have a 3-inch drop. I do not want to raise it for looks or because it squats too much.
