I find my bag to be more than adequate. The tent would require more space to use, and may be harder to store. My bag rolls up into the same space required by a shirt. I have used it in the field to retrieve infrared film from my camera, and once to get a roll out of a camera that came off the spool in the cassette.
I'd also change the chemicals a bit. I know that rapid fixer sounds like you are taking a short cut, but actually rapid fixer is (in most cases) technically superior to 'regular' fixer. Regular fixer (as you have in your cart) uses sodium thiosulfate. It's the thiosulfate part that does the work. Rapid fixer uses ammonium thiosulfate. This non-metal containing fixer requires less time to fix, and less time to wash out than does regular fixer. And some materials REQUIRE ammonium sulfate to completely fix.
And indicator stop bath ... it's unnecessarily expensive. Stop bath is not needed at all, but is preferred by some people. It is 5% acetic acid, which, coincidentally, so is distilled or white vinegar. Or you can buy 28% acetic acid and a bit of phenolphthalein indicator and mix your own. But vinegar is so cheap (compared to developer and fixer) that you can just one-shot it along with your developer.
Finally the funnel and syringe ... Buy a funnel at the grocery store for a buck. Or develop your ability to pour from a large mouth into a narrower one. This skill will come in handy, and might prevent contamination due to a dirty funnel. And a 12 mL syringe is going to be too small for the HC110 if you ever plan on developing two or more rolls at once (it'll work OK for a single roll.)
Dang, now THAT was way more than 78 words! 😱
