Here's my two cents....
Many years ago our Onan up and decided it was tired of putting out electricity. The engine would run but the genny part didn't generate.
So I found a good deal on two Honda 2000i generators with the parallel kit.
Although it is a little cumbersome to deal with the two generators when we need to run the air conditioner I did find it very convenient to have portable generators. Here's why:
> If we only need one generator on the trip I only bring one and leave the other one at home.
>We had a 35 hour power outage at home. I hooked up the refrigerator, lights and TV to one of the Hondas and we were the only house on the block that wasn't dark.
>A friend was building a cabin in a remote area, we used one of the Hondas to power the tools and compressor
There have been a few other times I have found having a portable generator (or two) a very flexible solution to replacing our dead Onan.
