What is an appropriate speed to drive on the expressway while towing?

What you missed is the faster you drive, the worse your fuel mileage. This requires you to stop more often to refuel which cuts in to the time you saved by initially driving faster. If you argue that your tank is larger allowing to go farther, you still lose additional time refueling your 50 gallons verses my 30 even if we make an equal number of stops.
If you look from the maintenance side, you have to run the engine and transmission harder (hotter) and put more centrifugal forces on your tires and lubrication. All of these things will have a shorter life span if you're pushing 20% faster over the same distance with all else being the equal.
The 160 mile difference mentioned above is almost 3 hours of 55mph driving time. How long does a gas stop take anyway? The slower driver gains back maybe 10 miles by skipping that stop.
As others already said, their time is most important so they're ok with the shorter vehicle life span.
