RTIC may be cheaper than yeti, but they are made in CHINA, like most other crap nowadays. The yeti tundra's at least are manufactured in Iowa and Wisconsin, along with the Philippines. I would rather spend more on American made, but that's just me.
I have the 65 yeti and love it. My cousin bought the 110 and it's a beast. He subsequently went and bought a 65, so now the 110 sits in the garage for most trips.
http://www.rokslide.com/gear/essentials/363-the-big-cooler-showdownThe above link has some great information. Something that is essential to know, a Yeti 45 does not have 45 quarts of capacity. The actual capacity is much less. Seems Yeti is the worst at loss of capacity over what the size is listed as. Make sure to look at the actual inside dimensions and compare those as opposed to advertised size.I will agree with what others have said, it may be best to buy two smaller coolers than one larger one. A cooler works best when it is full. If you only half fill it all the time, much of the ice is just keeping air cool. I have a Yeti 155 and a Yeti 45. I use the 45 way more often. I have the 155 for 7-10 day raft trips and for a refrigerator during hunting camp. I do like the rope handles as they can be adjusted to what length I need them to be. Also, the wire trays that fit in the top of the cooler is nice keeping some things out of the bottom (cheese and fruits).
