I think that this trailer is within your capacity, if only just.
The Ridgeline has 600 pounds of tongue weight capacity- nice on a rig that only allows for 5,000 pounds of trailer! And a good thing since according to my quick look at the manual just now, Honda recommends against the use of W/D.
Do be advised that the tow limit is based on two occupants and drops by 250 pounds for each additional person. Presumably this number includes the weight of their gear, too, and doesn't represent Honda's opinion on the average user's weight!
