In todays world of everything-is-disposable and I'll-just send-it-back I bring the story of my Sumo Suction Rod Carrier from Rodmounts. I purchased them new in 2011, HERE and they have been through the ringer over the last 10+ years. Multiple vehicles, several states, salt and fresh water, and even tumbled down the highway when the suction broke free, most likely because I had them on for a few weeks, not what they were designed for.
I gave the old suction cups a wash and Armor-All'd the plastic and lubricated the ball and socket plastic joints. The replacements went in easy and now the unit looks almost brand new. So why does this work for me? In 2011 I was living in Ocean Township, just a quick ride to the beach so that's one, when you want to jump from say Marine to Whitehall its a quick ride on the outside which eliminates the broken-rod-tip-in-the-door move, and great for the Upper Delaware where you're jumping from say Junction Pool to Long Flat in a hurry, perfect for anyone that has a beach buggy pass for Island Beach State Park, and more recently using them for the Trenton to Scudders move
after the 9 foot tide drops out. Now, surprisingly they haven't been stolen yet, which means I just jinxed myself for this year. I wouldn't leave them on for a third shift in Trenton where I am fishing far away from car, someone will surely grab them, even if they don't know what they are. I plan on getting the other set so I can confidently drive around without the suction being lost, I have lost one of them on the road, and have driven with the rod perpendicular to the hood when I have forgot to secure them in.
If you are thinking of this, I recommend it, you can see more on the Rodmounts website, HERE.
