Do these jacks mount to my RV frame or do they sit on the ground?

These are designed to be positioned under the frame and operated from the ground—no drilling or permanent mounting required. Place them at your leveling points and crank the handle to raise.

Will polyurethane hold up if I leave the jacks outside during the off-season?

Polyurethane resists UV and moisture better than steel, so seasonal storage outdoors is fine. Rinse them clean and let them dry before packing away to extend life.

What happens if I exceed the 5000 lb rating on one jack?

Overloading causes the scissor mechanism to bind or collapse unexpectedly, creating a safety hazard. Use both jacks together and distribute weight evenly—never load one jack beyond its rated capacity.
