How high can this ships go? How Fast?

All along the Andes in south america there is a dire need to efficiently move products from high altitude to the coast (where major cities are)

In Peru for example, there are hundreds of small farming towns sitting at 10'000+ feet of altitude but just 40 straight line miles from the ocean.. Today to get there, trucks have to use one of the few roads that ,zig-zag up to the high lands before heading into any of this towns. ( an 8 to 16 hour trip )

Being able to ship produce straight down to the big cities on the coast would be a game changer.

One of the issues with getting that high is that the higher you go, the less buoyancy the airships have, and you'd need bigger ships with more gas to haul the same loads. But the sky is very big, so it might just be an economics of scale problem

In this case, ships will be heavily loaded on the way down (carrying heavy produce) and lightly loaded on the way up (carrying lighter products like medicine or high value manufactured goods)
