You have the same family of four and Ridgeline tow vehicle that I do. My family has a Fleetwood Sante Fe popup that we've used for the last 7 years. I've been thinking about moving to a hard-sided trailer and so have been lurking on this forum recently to learn about TrailManors.
I also targeted the 2720 and 2417 for reasons you mentioned. Honda does not recommend using a WDH, so tongue weight may be an issue with these trailers. I'm curious how many inches a fully loaded 2720 will drop the rear of the Ridgeline.
I love my Ridgeline. In 2016 Honda is supposed to come out with a new version. Maybe Honda will add to the towing capacity and change their position on using WDH.
I'll return to lurker mode and learn what you find out.
