The airtight seal, security of the box is the same across the board, but if you stand on a 30lt box for example, one will flex slightly the other won't.

I had vaguely thought that the connection plate was the same three point system - but without a brochure infront of me I could say for certain... this is trying to drag the information out of head that was buried over a year ago when I was last at work!

I will say that their brochure is one of the hardest to order from unless you know Givi's 'system'... which is why they ran an orientation course that I went to in their distribution centre in Daventry.

Can I also say in my defence that I only sold the things and have never, ever, had one on eany bike of mine.
