Carrying gasoline for generator

The GP3600 is a gas generator by the looks of it?
The smallest diesel is the XD5000E

But that’s the point, it doesn’t say you can’t.

 

The problem is as elroy pointed out on that, 519$ is the cheap gas version, amazon has the diesel at 4500$, dont get me wrong, it doesnt look half bad, but ummm, not the right price

 

My predator is quieter than any diesel apu and with ac is less than 1/6 the cost of a apu.... that includes the ability to charge the batteries and run a block heater

 

ALL open frame generators are LOUD..... I find it strange that this one doesn't list just how loud it is....

For comparison normal conversation is 60db.... Honda eu3000 is 59db, my predator is 58db... I currently have mine on the catwalk 1 1/2 ft from my bed and when running I almost can't hear it

 

Quietest open frame longest run time generator. Few db louder than honda but remote start, 22hr run time.

Don't mean to change the subject...
