These coolers may keep ice for 5 days at 90 degrees (I have not tried this particular test, yet), but their construction is shoddy. there is no difference between this cooler and the marine version, except for color, so save $10 and buy this version. see my review of the Marine version for details.)Examples of shoddy construction:-the bottom part of cooler is constructed of two pieces of plastic (inside part and external part) with foam in between. The seam where the two pieces of plastic comes together is not sealed properly. In some cases this gap is about 3/64". This compromises the integrity of the cooler. (This was way more prominent on the Marine version of the cooler. But, I have a feeling it is just inconsistent manufacturing and some Coleman coolers will be more screwed up than others, regardless of model. Wish I could find a store that carried them, as I could pick and choose and find the least crappy one, instead of ordering online and playing the lottery.)-hinges are cheap and thin plastic that I suspect will break in less than a season-handles are cheap plastic held together by cheap plastic pins (doubt they last more than one trip)-drain plug is cheap plastic cover type and not screw type-no basket to keep dry things dry-inside of lid looks like it has channel for rubber seal, however, A) there is no seal and B) more infuriating is the fact that in 8 little places and one larger place near handle, this channel is missing, so you cannot even put in a seal yourself to completely seal cooler.-no latch on frontIf you want to purchase this Coleman Xtreme 70qt cooler, I would make the following mods:1 pull out pins on plastic handles and replace handles with rope2 replace hinges with stainless steel3 seal seam between two plastic parts of bottom section of cooler4 buy appropriately-sized cheap freezer basket and rig inside cooler to keep dry things dryTo go crazy with your mods you can add the following:5 add foam seal to channel in lid where you can6 add a couple draw latches to front7 add some non-skid rubber feet8 replace drain plug with screw typeThen you might have a decent cooler. Or you could bite the bullet and get a Yeti or Engel which are built like tanks.
