In Massachusetts, I run into some BS dealing with trucks. I have an 84 GMC C30 rated for 11k. 2wd with a dump bed, 4speed and a mild built small block. Weighs in at 6k, light for a 1ton dump. It has the heavy duty 14 bolt with huge drums, bigger and thicker C&C FRame with re-enforcement from the factory (more that I added) new 13 pack leafs with helpers, 6.2 diesel front springs and lower control arms (cheap way to lift the front of a gas square body and get the bigger springs). The lower weight is a 2wd reg cab, gas engine, no computers/safety **** and a sparse interior. Keeps the payload high relative to the registered weight. Now…I have the truck registered for 10k even. I have to register commercial ($200 for 1 year) since it’s dual wheels. At 10,001 you need a DOT inspection. I don’t need to. But every year I have to remind the inspector that it’s commercial/nonDOT. I hate going it’s always a problem but I always get a sticker.
