Yes, just top it up when needed (should take a few weeks to drop enough to bother if sentry is off) However, I suggest doing something to protect against critter damage while it sits there. If weather is favorable, 3-4 days ish. Which covers it for a few weeks without a cord running along the...

It's more handy when unhitching. However, being at the hitch to give it the extra rock and keep ball lock open is helpful.

Huh? The receiver test spec for an 11k trailer rated vehicle is around 6,000 pounds, not 1,100.

I would LOVE for Tesla to provide WD guidance, especially since they used it in on-road testing. I'm less worried about the structure as regards crash design since they have two energy absorbers between the casting and bumper. Now, do we want to get into how their cargo carrier guidance...

Let's table the cargo carrier side of things for the moment because it's a whole different set of dynamics and we agree on the leverage principle. Agree the WD dynamics are different due to the stiff structure. So let's dig into the details. We'll use the receiver pin as the reference. A 11k...

Yep, that's to use UWB for automatic frunk opening.

The trailer tongue weight which reveals trailer CG vs axle position and therefore stability is measured at the ball. I 100% agree with that. What I am speaking to are the forces at the truck's receiver which knows only the loads imparted by the piece of 2" square tubing inserted in it. This...

Sounds like what happened:

Only when stationary. Otherwise, please explain SAE J684 and Directive 94/29/EC for Europe.

They don't make the truck stronger, but they do allow the truck to handle a higher load... Therfore, they must be modifying the forces the truck sees to acceptable limits. IOW, the make a higher hitch torque look like a lower torque (like a lighter tongue would).

Force on the ball is not the same as force on the receiver. Loading the spring arms (green) increases the force on the ball and applies a torque that counters the trailer tongue weight. Raising the trailer (purple) also increases load on the ball and decreases torque on the receiver (same...

Don't know. But I discovered last fall that the tire monitoring does figure out that you purposely aired your tires down after a bit of driving.

Ohhh that's fun! I wonder if it's load based? Only all terrain tires have a known psi range though.

The two equations which need to balance out are wheel loads equal total weight and wheel loads and weight torques sum to zero. The hitch point dynamics fall out from that. The force imparted by your feet becomes additional load on the trailer axle. In the extreme case, one could lift the rear...

Wait are we talking about AEB or AP/FSD? If the latter, how did Mark get AP to drive down the center line?

Are we talking anti sway hitches or weight distributing ones? Weight distribution hitches produce torque opposite of the tongue weight while also decreasing what the receiver would perceive as weight. Image the trailer was reduced to a point load on the ball and you lifted on the spring arms...

Sort of similar from China

It is designed to tow an 11k trailer with 1,100 pound tongue weight which means the receiver is designed to withstand much more than 1,100 pounds. In other words, if it broke at 3,300 pounds, that would be a fail, not a "great! it handled 3x what it needs to".
