I use RAM Mounting Systems products in my boat, RV, Jeep and other vehicles. They make a bracket and mount for about anything you can think of, and the reason I use them is that they work, they're tough, and they do what is promised in their marketing.
This pic shows the Ram-Rod Light Speed holder that is in my video below. Wow, this baby is sweet and works great -- trolling, stationary fishing, or just temporary set your rod down where it's secure, yet easy to grab.
Also pictured (besides the leaf litter in my boat) are the RAM cell phone/Spot holder and the RAM GPS holder for my Garmin. And yes, that is a custom, Del-Built, Roll Bar over the console -- smile -- not really a roll bar, but it's a great grab handle and brace (leaning post).
Now enjoy my short video of the Ram-Rod Light Speed Rod Holder.
