Strongly thinking of buying a flip over. Most I will spend is $550. I want a 2 person but as light as possible and no longer than 60" so I can get it loaded in the back of my pickup, close the tail gate and not getting a hernia doing so. I want insulated. So I have it narrowed down to Otter XT Cottage, Frabill Aegis 2250 or the Eskimo Sierra thermal. Currently I am leaning towards the Frabil. Any of you boys have any insight on these models or recommendations?
