I went yesterday and actually laid my eyes on one of these bad boys.

Not sure what the heck I was thinking but this thing is pretty big. It will definitely get the job done.
Getting dual EU3000i's would mean handling 2 separate 131lb units anyway. And cost wise 2 of these is close to or a bit more than 1 7000.
The EU3000i Handi looks great at 78 pounds, but I'm sensitive to noise level in the camp grounds.
So I'm thinking ramp the EU7000i up into the truck at home and run it from there at the campground.
I'll get a BBQ grill cover or something to disguise it in the back of the truck when I need to.
