No ice for me for several years
I haven't carried ice for years... I use the cold packs (like are used to ship chocolate). I use up to about 7-10 of these artificial products at a time depending upon how big a cooler I am using. But I am rarely, if ever, camping and so it is easy to find a freezer in a motel that I can use to refreeze these gel-packs.

They're the only ones I've seen
The Ice Houses of America, dba "Twice the Ice", have 4 locations near to my home,including a new one just 1.5 miles away. As messy as it can often be, there is often no substitute for lots and lots of ice. If that's what you need, "Twice the Ice" works well. We've purchased several 100-150 quart capacity marine coolers full for wedding receptions and large oyster roasts, and at that scale, the savings are meaningful. Just be sure to bring lots of help to manhandle those coolers with 120-160 lbs of ice inside! They don't jump back up in the truck by themselves.

Ice chest cozy and mini-blocks
A few more ideas relating to ice and ice chests. A couple of years ago I took a quilted windshield sunscreen and fashioned it into a cozy for the cooler. It slips over the cooler top and covers the 'gap' between the top and base. It has extended the ice for our trips.

On this thread several have mentioned using reusable blue ice. As we seldom have access to a freezer this doesn't work for us, especially having to store them in between freezers. What does work is freezing 32 oz soda cups. It is almost like using block ice, which does last longer. We do this at the beginning of a trip, it lasts quite a few days. Once melted we can store the cups inside each other and use them again when we do have access to a freezer. Also, if they split or get lost along the way they are easy to replace.

Just a few ideas to enjoy a road trip.
Frozen food to keep the rest cold.
This reminds me of when we used to go camping with the family, all those decades ago. We froze the milk in litre cartons, as well as all the fresh meat we were taking. We had a large cooler (a bit like in your picture). This kept drinks cold for the 5 or 7 days we would be away. The first few days we would have to take out the milk before going to bed, if we wanted liquid milk for breakfast.
I like your cosy. Am now thinking of something like that for my fridge. Not that it is not running extremely efficient, but, who knows, it could still run more efficiently.
