Thanks for the insight.
I have plenty of time to decide as trip is not till middle o 2026. I prefer the 48 Can Polar and hope it comes available again. I will watch the web site closely. The RTIC brand has Lightweight versions one is 52 QT at 21 LBS the other is 32 QT at 13 LBS without wheels. I think both would be OK for the trip. Just have to watch the total weight.
Just take it as a carryon we do every time👍
