If it’s going to have enough capacity- it’ll be heavy. My 2k Yamaha is about 45 lbs without fuel... and you really don’t want to drive around with gasoline in a container!
Would most likely need a 5000 watt generator that has 240 out of it. These are bigger and heavy units that come with wheels to move around. Some start at about $600 or so... or get a Honda 7k for about $4500...!
