Ortlieb Water Bag?
Hi. I'm planning a longish tour (SF to Texas) and shopping for necessities and maybe luxuries. I'm looking at the Ortlieb Water Bag which can be fitted with a shower valve. It comes in 4 liter (about 10 pounds of water) and 10 liter (about 22 pounds!) sizes.
Is this a reasonable thing to take along? It seems like a huge amount of weight, but of course it's easy enough to find uses for water. Otherwise I'm planning to take three water bottles plus two Platypus bladders (1 liter and 3 liter, I think) I already own.
