The RV departure reminder that physically stops you from driving away before you're ready. Fits your coupler like a real ball. You can't hitch up until you remove it.
One moment of distraction at camp departure costs RVers thousands every year.
A 3D printed dummy coupler insert sized to fit your trailer's ball socket. Your coupler latch clicks right onto it just like a real ball. Bright orange tag hangs forward, visible on your backup camera. You physically cannot hitch up without removing it first.
Not sure? Check the sticker on your coupler — it will say 2" or 2-5/16".
⚠️ NOT a security device. NOT rated for towing. Departure reminder only. ASA plastic — UV stable and weather resistant.
Real stories from real RVers. We've all been there. Share yours — it might save someone else's rig and their marriage.
"Pulled out of the campsite at 6am. Got half a mile down the road before my wife spotted sparks in the backup camera. Shore power cord had been dragging the whole time. Ripped the inlet clean off the trailer."
"Drove a full quarter mile down the campground road with both rear stabilizers still deployed. Sounded like a tank. The campground host came sprinting. I am never, ever living this down."
"Left the sewer hose connected. Realized it when I saw it flopping around in the side mirror at 35mph. It had been dragging for about 2 miles. The campsite behind us was not pleased."
Did you drive away with something still connected? Own it. Share it. Help a fellow RVer feel better about themselves.
I'm a Venture Stratus owner and fellow RVer based in Burleson, Texas. Like a lot of you, I kept hearing the stories — shore power cords ripped out, sewer hoses dragging down the road, stabilizer jacks grinding across the pavement. And I kept thinking: why isn't there something that physically prevents this?
Checklist apps don't work when you're tired and rushed at 6am. Sticky notes fall off. You need something that makes it physically impossible to drive away before you're ready.
So I designed the Dummy Ball — a dummy coupler insert that latches right into your ball socket while you're parked. You literally cannot hitch up without removing it first. That's your reminder. That's your checklist trigger.
I made the first one for myself. Then my wife smiled at it. That's how you know it's a good idea.
