100% agree, those boxes are going to bend within 50m of filling with the thin steel sheet and 40kgs hanging off them. I understand why you have gone this way however the loads into the arm and then the bearing are far greater than a flatter side by side config. Your latch is going to take a pounding if you dont have some sort of load bearing guide assy to take the vertical and twisting load - you dont want the catch to do this. I would be conceptually mimicking a Kaymar style to be honest ( support guide bracket to take the vertical and to line up the carrier with the clamp.), but even then they rarely if ever built swing aways with the jerry cans in that config, and their bearing system is a bush rather than a roller bearing, which is set up for higher compressive loads.

Yep. Bracing the back was always on the plans. How? I have not yet decided. I will lower where the holders are welded to the swing away, as much as i can so there less on top.

Just thinking if using T section steel will be better for vertical support over using say 3mm x 25mm square tube, or even 25x50mm RHS.

Maybe to have a length of 25x50 RHS running left to right across the top of both holders, as John suggested, then run a dead vertical brace from that down to the swing away and also from the top, on a angle down to the back of the swing away. Not sure yet.

If all this doesn't work its no big deal, i enjoy working with steel so I'll just start again if i need too.

Just had a thought.

If I were to make the rear bracing similar to the bracing design for the spare wheel carrier, which takes a similar if not heavier load it should work.
