Aaron, good question - the Transformer # PA66VR is rated for slopes up to about a 4% grade, which translates to roughly 2–2.5 degrees of slope. Since your driveway measures around 3 degrees (about 5%), that’s just above the safe operating range. It might still work for short moves if the surface is smooth and you go slow in low-speed mode, but Parkit360 officially recommends keeping it under that 4% slope limit to prevent runaway load risk.

The built-in Smart Brake system will hold your trailer automatically when you release the joystick, which does help with control.

Is your surface concrete or asphalt? That will make a big difference in how much traction you actually get.
