The lil 2kva one we got atm seems to power most stuff so a 3kv should bemore than plenty
Trust me on this one ian, 3kv is only just enough to boil a kettle. your only gonna pick up 800w over your existing unit and as we saw it might well power things but the voltage drops and things stop working.
A hookup is 16A a 3kva genny is 12A that other one is 18A
I admit the comercial units are big that unit is 900x500x700 which i believe would sit in the front section of the BBQ between the lockers. With the addition of some strap downs it would be fine in transit
