If they went back on sale like they were i would get a 20 as well. They were ridiculously cheap there for a minute when they were liquidating the old stock.
Revisiting this: went down to Port A Thursday to help in-laws with their beach house and packed my 20 with various drinks. Was only planning 1 night stay but unfortunately the damage was worse than thought so I stayed thru today. The 20 is just a bit small for a stay longer than 1 night. Picked up a 30 today at Buc-cee's Wharton in new sea foam color on way home today.
