I know my GVWR and GCWR. I work to remain under those weights. It is difficult to find any RV with sufficient GCWR and GVWR left for normal use. I actually looked at a 36' Super C that was over the GVWR when it left the factory! Some of them had 500# of CCC left without water most were over! I only found out by calling the factory rep and asking what the shipping weight was and the NCC (net cargo carrying capacity) was. He didn't know (the factory rep) and when he returned he said that it seemed that they had been shipping many units overweight from the factory. It is common to put a 10K hitch on a DP but the unit only has 4K of GCWR left if loaded to its max GVWR. This makes it very difficult for the average customer to realistically determine what they are doing. I will have my unit weighed and try to manage within the specified weights because I'm paranoid. Some weigh stations demand that all vehicles over 16K stop at weigh stations even RVs. Technically they can write you a ticket and take you out of service until you reduce weight.
