Not even close to true. The difference between a 3/4 and 1 ton truck when it comes to actual ratings is just as vast as the difference between a SRW and DRW 1 ton
Not when we look at those mfg website specs from GM...Dodge/Ram...Ford I mentioned above. You either agree with them or disagree.
Agree a one ton srw and one ton drw is nite and day different but in most cases a 3/4 ton and one ton srw have the same mechanical specs/ratings.
Check out those mechanical specs and you too will see how the same or close to the same the 3/4 ton and one ton srw are.
In many cases the only difference is the door tag GVWR placard such as Fords F250 with the heavy service package/camper package has the same uprated suspension/same truck/ as F350 srw.
