Yeah, the price difference between what analyst estimate it costs Tesla and what we would pay retail per kilowatt-hour of capacity still remains a major obstacle for RVers to use much more of this technology.

Some rough estimates I've seen have placed the truck's battery bank at a minimum capacity of 800 kWh, with some estimates much higher. Tesla stated the truck needs less than 2 kWh of energy per mile, so the 500-mile range suggest a HUGE battery. Some speculate 8 X 100 kWh modules from auto model.

For comparison, let's look at a typical flooded golf cart 6-Volt battery rated at 1.5 kWh, giving .75 kWh of useable capacity at 50% depth of discharge. That semi battery is therefore storing at least as much energy as 1,000 Trojan T-105 batteries. Granted weight and costs are off the chart, but if only 5% to 10% was economically viable, we'd have the equivalent of 50 to 100 Trojan T-105s.
