According to the Ford Website, the GVWR for the Ford F750 is either 30,000 or 33,000 lbs depending on how the truck was configured. http://www.commtruck.ford.com/ctw/default.asp
The F750 was not in production in 1965.
The Ford F750 has a higher Gross Vehicle Weight Rating, and more powerful engine options available.
The F750 was not in production in 1990.
Depends on what the Gross Vehicle Weight Rating of a vehicle is. For something like an F750 which is licensed at 26000 lbs or less, you don't need one. 26,001 lbs. GVWR or more, you'll need a Class B.
A Class A CDL is for commercial vehicles with a Gross Combination Weight Rating of more than 26,000 lbs., in which the vehicle in tow (i.e., the trailer) has a Gross Vehicle Weight Rating of more than 10,000 lbs. Most commonly, this is used for tractor-trailer combinations, but it is not exclusive - for example, something like a Ford F650/F750 pulling an equipment trailer rated at more than 10,000 lbs. would require a Class A CDL. Class B CDL is for single vehicles with a Gross Vehicle Weight Rating of more than 26,000 lbs., or for combinations with a Gross Combination Weight Rating of more than 26,000 lbs., when the weight rating of the vehicle in tow (trailer) does not exceed 10,000 lbs.
Manufacturer's GVW is 31,000 lbs.... legal GVW depends on what it's registered as... if it's registered as a 26k truck, then that's the legal GVW. If it's registered as a 33k truck, then that'll be the legal GVW, and a CDL is required.
If the 750 is unladen, yes. The tare weight of the F750 is well within the towing limit of the F350.
Anywhere from 20 to 300. A Class 8 truck is simply a truck with a Gross Vehicle Weight Rating in excess of 33,000 lbs. Not just tandem axle trucks, but, as an example, the current production Ford F750 falls into the Class 8 category.
36 to 40 oz
The F750 is sold as a 26,000 lb. GVWR vehicle, but actually has 31,000 lb. axles. If it's registered as a 26,000 lb. vehicle, and is not loaded over 26,000 lbs., then no, you don't need a CDL. If it's loaded to a gross weight of over 26,000 lbs., or if it's registered and tagged as a GVW vehicle (or whatever your state's classification for a vehicle over 26,000 lbs. is), then yes, you do. Now if it's not registered as a vehicle over 26,000 lbs., but you're towing a trailer with it which brings the Gross Combination Weight Rating to over 26,000 lbs., you will need a CDL - Class B if the weight rating of the vehicle in tow is 10,000 lbs. or less, Class A if the weight rating of the vehicle in tow is more than 10,000 lbs. In any instance where it's transporting a quantity of hazardous materials which requires placarding, or is a bus designed to transport more than 15 persons (including the driver), you need a CDL with the appropriate endorsements, regardless of what weight class the vehicle is registered as. If it's registered as a 26,000 lb. GVWR vehicle, you would need a Class C CDL with passenger or hazmat endorsements. If it was registered as a 33,000 lb. GVWR vehicle, you would need a Class B CDL with passenger or hazmat endorsements.
Class 8 simply means a Gross Vehicle Weight Rating of more than 33,000 lbs... to that end, the Ford F750 from 2011 onwards had a manufacturer's Gross Vehicle Weight Rating of 37,000 lbs., making it a Class 8 truck... however, if you're thinking of tractor-trailers and tandem vocational trucks, no... they sold that division to Daimler A.G. in 1997... Daimler A.G. subsequently manufactured them under the Sterling name, and took them out of production in 2009 to focus on the Freightliner and Western Star brands.
Depends on what the gross vehicle weight rating of the truck itself is. If it's under 26,000 lbs, then no. Single axle trucks can be a bit ambiguous as far as this is concerned. One example would be the Ford F750, which is built to be a 33,000 GVWR vehicle, but is marketed as a 26,000 GVWR vehicle. So long as the weight of that vehicle remains under 26,000 lbs. GVWR, it doesn't require a CDL. Tandem trucks and larger, however, are not so ambiguous - you need a CDL to drive them, no matter what. Unless it is exempt.
