But you cant use a 15T MAM vehicle combination, the total must be 20t.Numbers are off but size is right. Most manufacturers use the same chassis from 7-15t MAN even use the same axles upto 12t
What I did my test in was physically no bigger than a 7.5t towing an ifor trailer. Just plated heavier.
As far as I know Ifor dont make an air braked trailer so that cant be over 3500kg either.
The trailer must be carrying 3t & weight at least 2t unladen.
A CE combo must actually weight 15t at all times.
Its GTW must be over 20t.
Yes some sue the minimum possible to make it easy / cheaper to run.
People will always do that, but clients also choose trainers based on vehicles that are close to what they want to drive after.
One local company only did wagon & drag, another only artic. Both lost out to each other as clients wanted one or the other.
I use a small (but well over min spec) vehicle for C1 BUT its not about the vehicle its about the training I give.
I thought long and hard before using a smaller vehicle to do it.
But in the end I train to think & if you think correctly you can drive anything.
