Bear in mind that UPS uses a wide range of vehicle sizes. The smaller package cars include Dodge Caravans (presumably the Dodge model.. UPS has their vehicles debaged), Ford F series with a box body, Mercedes-Benz Sprinters (both with regular van and box bodies.. these have also been sold in the past under the Dodge and Freightliner marques)
The "classis" UPS package car with the round headlights were built either on Ford or GM chassis by Morgan Olson and Union City Body. The newer ones with the square headlights are built on Freightliner or Navistar (International) chassis, and I believe are assembled almost exclusively by Union City Body.
As for the tractor-trailer fleet, they use a range of vehicles... Sterling (as well as the older Ford Louisville), Mack, Volvo, Freightliner (the latter two primarily acquired from their buyout of Overnite, which became UPS Freight).

Yes in most cases UPS does service its own fleet of trucks. This is also true with the airplanes tht UPS uses to deliver worldwide.
UPS (brown trucks) is completely separate from USPS.
Brown, in the USA.
Freight trucks are 13'6". The delivery trucks are slightly shorter at around 11' or so.
no only weekdays.
United Parcel Service of America is known for their brown trucks. To be more specific the color of these trucks is Pullman Brown. These trucks are known internally as package cars and are nicknamed "brown". In addition to the brown trucks UPS also operates an airline.
It depends on where you are on their route.
They are Black everywhere.
