Question: too much camper - too little truck

Airbags will level the truck, but won't add as much stiffness as more spring. Pay attention to what's actually rolling. I personally get a little camper roll before the truck begins to lean, and when it does lean it's not that much. You can feel the camper doing its thing though. I did Bilstein shocks, airbags, Hellwig rear sway, front Lance camper shocks, and most recently added another upper overload. It was a double whammy because on one hand it added spring, but being an upper it pushed both upper into the frame horns sooner just like a stable load would do. If your E tires aren't aired up to the max that will also make an appreciable difference.
