Nice. But you don’t take reliability and breakdown concerns in your calculation regarding dump trucks. Especially if they are being run 24⁄7 in night and bad weather conditions, allow for a nontrivial fraction of them to be broken down and under repair at any given time. This could be an enormous problem for the first few years of action because repair and maintenance services don’t exist in such a high concentration to handle so many heavy vehicles in a remote location.
Also, see how many such vehicles are owned by the US National Guard, Seabees, etc. They may not be listed in the FHA’s statistics.
Thanks for your careful read. I suggested 160 hours per week operating, which allows for 8 hours a week for fueling, scheduled maintenance, and unscheduled maintenance. This is probably optimistic, but I think my estimates are low by an order of magnitude compared to what we could do with non-dumptrucks (though these would likely require retrofitting).
