Nope.
It is mechanically connected to the road ... at 1 MPH , 5 MPH or 50 MPH ... etc ... there is a finite limit to what the transmission can convert that to for what the ICE sees ... and the transmission is not a 100% efficient thing either... the connection to the road is itself a limitation that the generator option as a tool does not share.
And least we forget ... the Generator can have the automation option to power my house in the event of a black out ... the pusher trailer can not.
So no... the pusher trailer does not have all the same automation options.

It is an advantage when one stops at a rest stop that doesn't have a EV charging plug ... the pusher can't help you when the vehicle is stationary ... the generator can... saying you don't want to do that stationary generator function ... does not remove it as a pro that the generator can do that the pusher can not.
A bigger alternator ... or any alternator at all for that matter ... on the pusher ... just turns it into a combination of both a pusher and a generator ... as long as you are anti-generator ... the alternator is not an option.

It makes sense ... It is just too heavily one sided / biased in favor of the Pusher for my tastes ... To me ... I see pros and cons to both ... trying to pretend the pusher wins in all categories ... as if their is no situation where the generator isto me seems like ... just turning a blind eye to the actual pros and cons of the two... and I see it as just incorrect.
I don't see it as simple as A = always better than B ... for either the Pusher or the generator.

Here I'll show you a few ... but there are others as well.
#1> Generator out-performs pusher.
Low SoC ... pull into rest stop to pee and eat ... this rest stop does not have a EV charge port ... Pusher gives you ZERO ... while you are there for 30 minutes to an hour ... but the Generator could have given you more than the ZERO ... More than Zero is better than Zero.
#2> Generator out-performs pusher.
Many Hours of Grid lock traffic on a 120+ degree day ... your EV as Air conditioning so you don't have a heat stroke ... but the pusher trailer just doesn't seem to be able to help the electric AC in the BEV with your stop and go grid lock traffic ... as you spend far more time stopped than moving ... but a generator option would still work fine ... and power and charge things fine.
#3> Generator out-performs pusher.
House generator during a black out.

Those are the easy three situations ... that are just an inherent con of the pusher trailer system , compared to a generator style system.
We can get into other as well if you like.

Both systems have pros and cons ... neither is the best option for all situations ... pretending or claiming otherwise ... to me ... is just incorrect and too biased on one side.
The pusher trailer will likely have lower bottom efficiencies than the generator trailer ... and the generator trailer will likely have lower peak top end efficiencies ... And the Generator trailer has some function the pusher does not ... which one will give you better net average efficiency ... or utility ... will very much depend on the specifics of the context of usage.
