Powering trailer with an alternator

I think there will be a loss of maybe 10% but I think I could power my trailer including A/C.
Thoughts?
Yes this can be done, with a special Bus high output alternator.
The inverter would need to be mounted close to alternator/ batteries and 120 volt wire to trailer.
Our rig is set up to do this (clicky below) but haven't used it because we don't have a travel trailer. I'm currently having a custom TT trailer built that will be able to power the TT's 120 volt AC from the tow vehicle alternator. The TT will have a generator also.
The tow vehicle's 120 volt system may be used to pre cool the TT while driving.
All in all putting these unique RV systems together from the best of boating, bus, semi-truck and European RV tech in a compact touring rig is my hobby. It gets real expensive and as many have already posted, a stand alone generator that is set-up to run while under tow makes the most sense.
