I know what GCWR stands for. Id have to ask a contact regarding enforcement for exceeding GCWR. I'm not saying a driver can't be cited for exceeding it, but given the variances when it comes to gearing and such on our level trucks I don't think that's something they would look at, i.e. a 4:10 geared truck can tow a 30,000 trailer, a 3:73 truck can also tow that trailer but it might only be rated for 27000 trailer. I didn't work commercial, and researched and dealt with things that were at the level I worked. Similar here when it comes to registration. Up to a certain weight GVWR (11500 I think) the weight fees are included, over that weight, then there is a scale based on set weight ranges.Ok but how about the GCWR, that is weight of truck and trailer together. Exceeding that is a problem from what I have read.
And many states you have to register your truck to the max weight allowed. (In Virginia). If I registered it as a car (not getting a truck plate), I could not legally tow the max GCWR. So they actually handed us plates that say on them 'truck'. And that costs me a lot more every year. I have a 3500 dually year 2005 4x4 4dr long bed.
