It will work, I use one for a camp shower and it folds up to tuck in the boot of the car............BUT (there's always a but) You might want to practice rolling it up before taking it out in public. The instructions show in bizarre illustrations how easy it is....the harder you try, the more it springs out and attacks innocent passers by...you will yell and scream
...then it pops into place like it was meant to. Now I do it first try, second nature, all in the wrist action, just need to twist at the right time. As for the heat, you can leave the zip door partially open to assist venting.
