> A 1.75 ton load, especially raised as high up as shown in this prototype, would flip the truck in the slightest of turns.
The battery in this truck is probably incredibly heavy, which really moves the center of mass down. The suspension is also computer controlled, and at high loads you could lower the vehicle to be closer to the ground. Carrying 3500 pounds off road isn't a good idea even if the vehicle can corner so you don't need the clearance.
Actually I think your overestimating the total weight, but it goes to the above point when you say
> Second, this is going to be a very heavy truck, 6000 pounds or more.
> Musk is imagining that battery technology will advance a lot before this thing ships
Unlikely, more likely he is just planning on putting a lot of battery in it. Unlike you, Musk has lots of engineers working on this and has a pretty damn good idea of what is possible.
Pickup trucks are ideal for packing a lot of battery, lots of space along the bottom to do so.
> Finally, the claim that the bed will extend to the ground to form a useful ramp. Nah. These folks have never lived with a pickup. No object heavier than a bicycle is going to make it up that 45 degree incline and into the bed without crashing into the cab before it can stop, especially given the polished floor of the demo truck. That's fantasy #3. No telling how much more reality distortion lies beneath that funky exterior.
ROFL - you realized they literally live demoed doing so on a ATV right?
Moreover, the main use of ramps, at least in my mind having unloaded and loaded a pickup truck, is making it easier to move heavy objects in and out by hand.
I'm pretty sure the only person fantasizing here is you.
