I definitely see this as something every owner will have to do around the 3-4 years. Again how you treat your ice chest makes a difference. Not that I slide mine all over the place but that does wear down those feet quickly so be mindful of that. Also that black deck padding does shrink and compress over time. Also installing that drain plug may be the biggest difference maker. Hypothetically you could reduce the full capacity carrying time by half. Because once you’re out of bait drain it and drive to the boat ramp empty!!!

Brother, I wish I had a good answer for you, but that depth of technology information I do not possess. However, you can reach out to Garmin and they might be able to help you out. I rely on them a lot.
