Two RVs? Three? FlatPad now saves a rig for each one — its leveling method and its size — and you switch between them right from the Visual or Audio tab. No more re-entering your dimensions every time you swap vehicles.

Calibration now finishes with an optional step to set your rig's size, so block heights are right from the first park. Skip it and FlatPad says plainly which default it's using rather than quietly guessing.

Keeping more than one rig is part of Pro. Everything you need to level a rig — visual leveling, flip-method calibration, block-height math — stays free, and still shows no ads.
