Canyon Coolers are super durable, and repairable and should be with you well into your walker years. If you accidentally break them they can be welded with a hot knife(best) or blow torch. I like them because they are built with plastic runners on the bottom so we can slide our 200lbs Canyon Coolers around the warehouse for years. Also, the cooler has phenomenal ice retention.
If you cooler is your seat? Height of the cooler should be a major factor to think about in addition to width. For a 14 foot boat I wouldn't get a cooler taller than 18 inches if I intended to use it as a rowing seat. A perfect cooler would go tube to tube and have friendly flush plugs(or no side plugs) that don't dig into your tube(future hole
. Canyon Cooler plugs are easy to adapt with a small hand saw if you find one that goes tube to tube. The next best thing leaves enough space for a water jug(next to the cooler) that gives you a stiff thwart like function and easy access for water
In your height determination don't forget a cooler cover. If you are relying on a paco pad this may sit you up higher than you thought.
