I was making a rhetorical argument. to me, $60 is a small price to pay for 1) a tank that weights about as much filled as a steel tank does empty
2) that won't gouge and scratch everything it comes in contact with (drybox, frame, drybags, etc)
3) if you crash into it you probably wont' get concussed.
4) and I can have a good idea how much fluid is remaining at all times without having to look for condensation marks or have to weigh it ...
I've never seen an aluminum tank in person otherwise I may have considered one. However they are probably priced more closer to the plastic ones than to the steel ones.
