Axles are weight limited which is the main factor.
Until around 2002 most DPs could carry the necessary weight on a single rear axle. That’s when multiple slides, tile floors, bigger engines and trannies push the weight over 20,000 lbs and a 10K tag axle was added.
Up until 2012 the weight limit was 20,000 lbs on a single axle but a highway bill changed it to 23K for buses and RVs making it possible to have 42’ DPs on a single rear axle.
Once you’ve on the tag axle, you’ll never go back to a non-tag because of the vastly improved handling and almost unlimited CCC.
There are some exceptions to that 23,000 lb limit. As an example, The Pennsylvania turnpike has a one axle limit of 22,400lb. And they will turn you back for very minor infractions.
