I wasn't being picky.
If someone based towing limitation on GTM, then consider a GTM of 2500. A 120 Series Prado can tow 2500. But a trailer with a GTM of 2500 may have an ATM of 2750 (GTM plus typical towball weight). No longer legally towable by that Prado. That's not picky, that's the law.
I agree with you re how GCM fits into the picture, and it's not picky to consider that - it's compulsory.
So many people just don't understand this subject, yet it's really quite simple:
- the trailer cannot be over ATM
- the trailer cannot be over GTM
- add the trailer actual loaded weight on the wheels (even if it's below GTM) plus the actual towball weight and tug actual loaded weight (even if it's below the GVM). The total cannot be over the tug's GCM
- the towball weight cannot exceed the tug/towbar maximum
- the weight on the tug's rear axle (or front for that matter) must not exceed the tug manufacturer's or certified GVM upgrade specifications
