Hey guys....
You CAN register and drive a 33,000 GWVR truck at say 26,000lbs. It all depends in how you register it. If your truck can gross 33k and you register it for 26k to stay out of ifta and what not, then you just better never have a gvw of 26k. You'll have to register each axle rating , so....with some trucks it's not worth it. Now if you have a 33k Gross truck, that weighs 19,000lbs empty......and you plan to haul say up to 12,000lbs.....then no, there is no way to do it, but if that same truck is only going to be hauling 2,000-3,000lbs, then yeah...you can do it.
The other question about cdl's. Keep in mind that some states require a cdl from 10,001lbs +. Some states also DON't require a cdl up to 26k.
Its tricky, but I would look at every state your looking at hauling in and make sure if you don't have a cdl. I know they save 40ft total length for a single unit, and some states will nail you for 42ft, but others will let you go.
I would just check each state law. Even though FED is wrote a certain way, states still have their little laws in place so they can get you, just make sure you do your research if you Don't have a cdl.
