This tool helps tiny house owners understand why their headlights are pointing at the sky when they hook up their trailer. It visualizes “Rear Sag” (Squat) and demonstrates how upgrades like Airbags or Helper Springs restore level towing, steering control, and braking efficiency.
It includes a Headlight Aim Visualizer to show the real-world safety impact of a squatting truck.

Performance Impact
Airbags vs. Helper Springs
Pros: Fully adjustable. You can pump them up to perfectly level a heavy tiny house, then deflate them for a smooth ride when empty.
Cons: More expensive, more parts to fail (leaks), requires maintenance.
Pros: “Set and forget.” Timbrens or SumoSprings replace your bump stops. They engage only when loaded. Zero maintenance, impossible to pop.
Cons: Not adjustable. Can cause a harsher ride on big bumps.
