I personally would want more like 65 mph possible or what's the point of dragging around 100s if not 1000 pounds of extra gear.
The added generator is also a bad idea. The ICE motor is the already 10 times more powerful generator.
I did see on the Jeep 4XE (supposedly the #1 selling PHEV last quarter) you can turn on and off the EV modes saving the battery for when you want, or put it in a generator mode where it adds to the charge. Pretty cool. And it runs 8.8 sec 1/8 mile drag racing although the guy did pull out the rear seat and spare tire (common drag racing hacks.) That's generation 4 or 5 Corvette territory. I bet 0-60 it would probably beat the c5 vette as the 1/8 mile is more like 0-75 mph.

The d!ck in me hates to side with the OP just on principle, BUT electric power produced by the ICE motor is likely to be brutally inefficient, especially at idle. He's talking about powering household/workshop type items, and a generator is the right choice.
Pulling 2000W out of a V8 idling is going to burn WAY more gas than pulling 2000W out of a 4000W generator.
A typical 4000W generator has a ~200cc engine vs. 5000cc of a 5.0L truck ICE (are there any that small? Mine is 7.4L). LOTS of fuel goes into just keeping the 5.0L mass moving, and it's going to have very high mass flow through it.
The most sensible way to make power using a generator is to size the generator such that the typical continuous run load is 70-80% of the maximum.
