Review on 🍔 Camco 28-inch Double RV Refrigerator Bar, Securely Holds Food and Drinks in Place While Traveling, Minimizes Spills, Adjustable from 16 to 28 inches - White (44073) by Eric Williamson

They are great with a small and cheap mod. Here is a description of Revain's replacement tips. "50 Packs Rubber Door Stops White Silicone Replacement Door Stop Caps Door Stops For Wall And Floor Protection One Size From Outus" will hold these and other Camco pull rods in place without slipping. Less than $11. They stretch to fit either end and you get 50. You could use alcohol on the wider end but I didn't. I keep the upper stem a bit loose so I can tilt it to get larger items out without having to take it off every time it's parked. The bottom bar stays in place. Or keep the top link taut while riding on the road. Once stopped, twist once or twice to tilt while still keeping the ground as you move.
