Jim i see you have a work truck, and as with mine all work trucks need work truck cup holders. It works real well for me. It'll hold a large coke from Hardees and a large coffee from the exxon station as well. I present to you the duct tape cup holder.
JB, Yeah I've actually used your cupholder. If the edge of the tape roll is tacky, it sticks the holder in place and works even better.
My truck has zero cupholders. I always drove holding my cup. Got kinda tricky turning and shifting but I got it done
FG, I do this a lot. If I'm holding the cup it rides up and down with me. But kinda tough to signal, shift, turn, and drink coffee at the same time. At least I'm not on the cell phone.
I bought one of the stainless steel coffee mugs with the screw in lid and rubber seal (goes inside the top of the cup), cost me $10 a few years ago in the wally world sporting goods department, and it doesn't leak a drop when it's laying on its side on the seat next to me
JW, One of my "SS coffee mugs" was a gift from one of my kids. I think he bought it at the dollar store. It leaks like a sieve, but I feel obligated to use it.
All, I also have one of those plastic "clip-on" holders. Those things are flexible, so they work like they have a built in spring. When the truck is bouncing on the freeway, the periodic motion stores energy in the springy cupholder until it practically launches the entire cup and coffee across the cab!
