I would think around 150-175 would be fine. 200+ may be a bit much. Just set the pot/pan on a folded towel as not to soften the rotomold. I usually use the hottest tap water (145 in my house) in 3-4 1 gal milk jugs to prep for FTC.

I would not. You just need to "Load the Heat to in it" . The plastic may expand fast and de-laminate from the insulation. Give it more time to absorb the heat if need be.  May have to change the water once or twice. At 150-160 you are just keep it at safe temp and not cooking it. And if you have the room keep a freshly heated jug or two along for the ride.

Where in Ma are you headed, no good Q here, but you can definitely get your fill of lobster and fried clams.

Maybe use a heating pad?

Also if you don't mind waiting in a long line hit up Red's in Wicasset or if you don't like lines Sea Basket.

Another great restaurant in the area is Primo in Rockland.  If you go there plan on getting there early, get a cocktail, and stroll the farm.  Belfast is a really nice little town a little further north from Camden where the Passagassawakeag meets Penobscot Bay.

I love the mid-coast region as well, I grew up just inland from Camden (probably 35 minutes without summer traffic), and do love the Rockport, Rockland, Belfast, Searsport area.  I agree about Bar Harbor being a tourist trap, at least during the summer months.  Don't paint the rest of Mount Desert Island with the same brush though.  Southwest Harbor is still a great little town and Acadia NP is one of my favorite places on earth - there is a reason it is one of the ten most visited parks (and 2nd most visited east of the Mississippi).  I firmly believe that seeing a sunrise from Cadillac Mountain is something everyone should do once.

It might not work for this trip, but if you go up again, I'd suggest looking into the Blue Hill area as well.

That's pretty cool, and neat that he done it. But I still would not risk warping or weakening a high end cooler. Again I'm basing my thoughts on what I have seen fooling with polypropylene at work. At a true 200 degrees, you can start to reshape it or reform it. You might get away with doing it a time or two, but ultimately I feel it will cause issues. If nothing else, I bet it will wreak havoc on the drain plug (cause leaks). I would at least ask Yeti or any manufacturer before I attempted it to see if it would void the warranty. It's kind of like me running some of my big units at 550 degrees. I did it a few times and now they leak around the seals. I haven't personally asked Yeti about using boiling water in their coolers, but I have a hunch as to what they will say. Just my thoughts. 

I'd just leave the lid open and put it in the sun for a few hours. I heated mine like that by cleaning and forgetting it all day. Pulled it in the garage at 6 and at 10 it was still warm.

@SGH just what is those pictures. 

That is polypropylene, the wicked stepsister to polyethylene which is what Yeti and all other rotomolded coolers are made from. We use polypropylene on subsea pipelines for protection. 

Mickey you could nuke a couple of wet tea towels and place them in the yeti.
 Our column heaters are roto molded and we set the highest hear limit to 90degrees C. Scottie has it right.  

I can't wait to try the corn on the cob trick.  

Should work. Closed car in hot sun might work too.
