Insulated fuel tanks?

[archenemy_6]

So currently I have a few mods installed the main ones are real solar system real fuels and those other real mods. KW space y and bluedog I think are my main parts mods. I've noticed that there's only like two tanks that say they have insulation. i think It's just a short 3.75m tank from kw and the stock 2.5m orange tank. Is there something I'm missing or is there a mod I can get to have a wider variety of insulated tanks?

Also I noticed that the fuel selection for the tanks is quite extensive but all the engines I have use only like 4 or 5 different combinations of the fuels. Are there any other engines that might use a different fuel mixture or anything?

I've never written (or had anything written) to give Bluedog compatibility with Real Fuels. I wouldn't be surprised if they didn't actually work.

I think so far I've just used a 1.5m tank with one of the engines I forget which one but it seemed to work fine. I believe the engine used kerosene or liquid hydrogen and liquid oxygen and had one ignition and it let me fill the tank just fine too.
