I am glad to see that not everyone assumed I was gonna spread out my "sheet" and homestead. I got some good advice on which to make a decision.
As stated in the OP it would be very rare for me to need a genny in the summer - we are winter wanderers.
So here is my plan. I am going to get the Honda EU2000i - the model that is set up for further add on of the parallel kit. The thing will always be in the bed of the pick up, whether in use or not. I seriously doubt that the need for summer air will arise and be high enough on my priorities that I will think it is worth while to spring for the extra bucks.
Thanks again to the folks that did not assume a whole bunch of stuff and also those that have been there and done that in Wally's parking lot. I feel confident that those Peterbuilts and others will have me outclassed when it comes to creating a disturbance. :C
