Hi & welcome to the forum. I think in theory it would work fine but a 4000W load must be a heck of a strain on the battery.

you are wanting to pull 16 amps from an inverter, you are going to need a lot of batteries to power that. why not get a genny instead as even running your tug's engine as a genny using the alternator is going to put the electrics under stress. you need a genny and a pretty big one at taht

3000W at 12 volts = 250amps. Wow

The bigger the inverter the bigger the losses.
Find some of my old posts i compared a 600w and a 150w inverter. The 600w one consumed more power even when running the same load.
I ran a 60w or 100w light bulb and the 600w inverter drew more amps than the 150w one.
Bigger is better but your losses will be bigger and worse.

I think to be realistic and practical you need to assess what power you will be using and how long for. The numbers need to add up.
Your proposal to install sockets from an invertor is fine in principle but you will need to think about protection as in protection against electric shock, overload, fire etc.
This will be 240 volt mains electric but without the safety features of normal mains derived 240volt electricity so you will have to provide them.

No expert, but we were always lead to believe that inverters knacker batteries!

High current draw knackers batteries, not specifically inverters.
If you're running multiple batteries, it may be possible to connect them in series for e.g. 48V at 63A for your 3kW versus 12V at 250A. You'd need a specialized inverter though.
Also remember inverters waste power even when not providing any load.
