Why drinks tip during a parked truck break
Check the drink, the support underneath and the movements around it before choosing a fix.
A small base is only one part
Steadi widens compatible drinkware’s footprint. But a sloped table, uneven bedding or a base near the edge can still leave the drink poorly supported. Start with a firm, level spot that supports the entire holder.
Make room for your hands and gear
A plate, moving sleeve, charging cable or paperwork can reach a drink placed too close to the activity. Set it beside you with clear lifting room. Move the drink before folding a table or shifting the items underneath it.
Check actual fit and seating
The container base must be 2–3.15 inches across, with full seating and suitable handle/boot clearance. A compatible diameter does not mean every tall or unusual container behaves the same way. Choose drinkware and placement thoughtfully.
Do not turn a parked-use example into a driving claim
A stationary scene does not establish behavior under braking or road vibration. Steadi does not attach to the vehicle, seal the drink or isolate vibration. Use the truck’s intended storage when preparing to move.
Clean the holder for the next break
Hand wash only and clean the supporting surface as appropriate for that material. Keep Steadi out of the dishwasher and microwave. It is not a liquid-catching tray or a guarantee against marks and spills.
