They have said there will be outlets but the amperage is not confirmed. I would suspect the 120 v outlets will be 20 amp for widest compatibility. My travel trailer runs fine on 20 amp as long as I don't try to run either the AC or electric heater along with any other big draws.
The Terra is supposed to get a 240v outlet and it will almost certainly be 30 or 40 amp.
If you get the Terra you could use an adapter to get the single leg 120v 30 amp outlet you want from the 240.
