Ability to utilize the new dually design with a 3/4 ton vehicle Yes No Enables a 3/4 pickup to pull same size trailer as a 1 ton dually Yes N/A So if I exceed the weight limits of my truck and have have an accident or receive a ticket will this company go to bat for me in a lawsuit or represent me in court
the density of steel (including stainless steel) barely changes with changes to the alloy (the same is true for aluminum alloys). All the steels fall in the range of 7.8 to 8.2 g/cm^3. (Around 0.3 lb/ft^3 for those still using the queen’s units). What changes dramatically is the strength to weight ratio. If you can make the steel much stronger, you might exceed the strength to weight ratio of good aluminum alloys. There is roughly a 3x difference in density between steel and aluminum, and the best steels can be more than 3x stronger than better aluminum alloys, so this works... in the end, it’s not that simple since toughness, fatigue, weldability, formability, corrosion resistance, etc all need to be thought about.
Someone should modify the (semi) standard trailer connector to have a standard backup camera pinout that passes thru trailer backup camera to show instead of trucks' backup cameras when the trailer is connected. Bonus points if Tesla made an extension that put side cameras on the trailer for its upcoming birds eye view. Not to mention putting batteries in the trailer flatbed.
