Thanks for the input. I did go with the Hennessy. I even used it "park to park" for my first ever tour here on Oahu. No issues, at least this time. A lot of interest in it from others at the parks. Up at Peacock Flats, there was a small group with two of them using Hennessy's. Of course, that's a whole different style of campground.
In case you are interested, I did a review of the Hennessy and posted pics from my ride here:
