Do you think that size is large enough for two people over 1 week assuming you only keep a days worth of drinks and rotate warm ones in at night?
Yes, the 50 is a lot of space considering you can pack it full (no ice). I could have prob gone with the 37 for my use, but the price difference between the two is so small that I went with the 50.
Remember that warm drinks will make the fridge run more until the drinks are cold. Something to plan around battery charging.
Some of my ice chest habits work well on reducing how much the fridge runs initially. I usually throw a few things in the freezer at home prior to loading the ARB.
- freeze meat, will be thawed by day 2
- freeze some drinks (thick plastic like smart water and Gatorade)
