I am not sure what a wheelhub powered trailer is? Are you talking about a pusher trailer?
"On the other hand 7kw would be much better at extending the range, 60 amps after power conversion losses could sustain speeds of 40mph as long as you have fuel and double the range of the pack at 65mph!"
I wouldn't be losing speed with the generator trailer, I was just commenting that at around 40 mph the generator could maintain that speed without the assistance of the battery pack. When I go faster it will use the 60amps from the generator and the rest from the batteries so speed will not be limited.
