To get the answer, you need to weigh your tractor trailer empty. When you get that weight, Lets talk numbers, this is wrong but it is a big example. If your tractor trailer is 35,000 pounds empty.

Gross weight or loaded weight is 80,000 lbs. Empty weight differs greatly depending on different tractor and trailer configurations but is around 36,000 lbs for a tractor and dry van trailer

Typically an empty trailer will take longer to stop. The reason is that the tractor trailer have been designed to work together loaded. The trailer does not get enough traction when empty so the friction generated by the trailer tires to contribute to stopping the truck is not great enough and the stopping distance increases.
It depends on what the empty weight of your combination (tractor plus trailer) is. You're allowed a total weight of 80,000 lbs., so, you subtract the tare weight of your tractor and trailer from 80,000 lbs., and you're left with what you can haul legally.
The correct use of the word Semi is to refer to the trailer, if a trailer has wheels in the front and back it is a 'full' trailer.

For interstate travel in the US without requiring oversize permits, the gross weight is 80,000 lbs. What that translates to in cargo weight depends on the vehicle's tare (empty) weight. Typically, a truck with a flatbed trailer will be good for 45,000 - 48,000 lbs., and a truck pulling a dry box can typically haul 43,000 - 45,000 lbs. of freight.
Number of variables here. It'll depend on the weight of the power unit (Freightliner makes several models), what type of trailer is being pulled, and whether you want loaded or empty weight. Empty, you can expect the weight to be anywhere from 27,000 lbs. and up, again dependent on the tare weight of the power unit and the type of trailer being pulled.
