This tool is designed to prevent a common and dangerous mistake: using “RV Stabilizer Jacks” (meant only to stop wiggle) to actually lift and level a heavy Tiny House. The calculator determines the specific weight rating required per jack to safely support your home long-term, factoring in a structural safety margin.

Recommended Hardware
Good only for stopping wiggle. DO NOT USE to lift the house off tires. Will buckle under load.
Suitable for leveling lighter builds. Look for “Leveling” rating, not just static capacity.
The professional choice for heavy tiny homes. Use a bottle jack to lift, then place a 6-ton stand for permanent support.
Crucial Concept: Stabilizing vs. Leveling
If you try to level a heavy house using only the 4 corners, you risk bowing the frame in the middle (like a taco). For houses over 24ft, always support the middle (near axles) first, then snug up the corners.
Never max out a jack. If your corner weight is 3,000 lbs, don’t buy a 3,000 lb jack. Buy a 5,000+ lb jack. Corrosion, uneven ground, and wind loads degrade capacity over time.
