depends how temporary and if you actually want to fish using them, rather than somewhere to transports rods off the floor. We don't fish from rod holders but do transport them with the rod butts dropped into a couple of lengths of plumbing waste pipe. Length of it Zip tied to the stainless back of each rear seat pods, does the job for those times of the years when we are fishing...like now-cod time! Luckily we have a source of supply for big releasable/reusable wire tie/zip tie thingies. So a couple of rods sit in there whilst travelling from mark to mark. They will be coming off again at the end of this month. The thingie in the top of the tube in the pic is the base of our metz aerial dropped in there outa the way whilst boat is in its garage, so I don't stand on it...again!
