What is the difference between the vandura 1500 2500 and 3500?

AnswerI BELEIVE THEY ARE JUST THE DIFFERENT WEIGHT CLASS"S LIKE MAX. LOAD WEIGHTS THAT THE VEHICLE IS RECOMENDED TO HANDLE

1500=half ton 2500=3 quarter ton 3500=1 ton

I have a Vandura 2500, it means a half ton with a three quarter ton rating, stronger rear springs, lower rear end ratio,& bigger engine....

I do believe that the 1500 has a shorter body than the 2500 and 3500. Also engine sizes, I believe that the 1500 typically comes with a straight 6, the 2500 with a 350 v8 and the 3500 with either a 7.4v8 or a diesel.

*My 93' G2500 vandura has a 1 ton frame w/ 3/4 ton brakes.*
