An inverter type generator runs at various speeds depending on the amp load demand. Saves a lot of fuel usually unless running under heavy load all the time.

Your 7kw gas runs at the same speed no matter what the load.

You may not even need the 7 kw's amp output capability and might be better off buying a smaller inverter type gas unit and mounting it on the trailer tongue.

There are quite a few units out there in the 3000-4300 watt output range and are inverters.

Diesels are great but big, heavy and the smell can be annoying.....
