What are the differences between the cadillac fleetwood and buick roadmaster?

Is the trunk alot smaller in the roadmaster? The roadmaster has 3 point lumbar support on the front seats and are heated like the fleetwood? and what is the weight of the roadmaster, and the size/legnth and width of it. Can the roadmaster come with a towing package? if so how much can it tow, how much cubic feet of space is in the interior of the roadmaster and how much is in the fleetwood brougham. are there any features that one car has that the other doesn't? if so what are they? Is the wheel base size/legnth the same, and are the tires the same size. this question is for the 1993-1996 models. and is the 1991 and 1992 the same shape as the 1993-1996 models?What are the differences between the cadillac fleetwood and buick roadmaster?The two cars are pretty much on the same platform as they have been for 60 years. The main difference between the two is engines and external sheet metal. All the rest is interchangeable I am sure that whenever they built a Buick or Cadillac, towing was probably the last thing on the designers mind. I am not even sure if they will have any specs for such. You can get the same options as a Cadillac so what each car will have is up to the person who originally bought it.What are the differences between the cadillac fleetwood and buick roadmaster?The fleetwood is on a "D" body whjch is longer than the roadmaster. The Roadmaster, Caprice and Impala SS are all "B" bodies. This is for 1991-1996 and of course the Impala SS was only made from 1994-1996.
