The Ridgeline has a higher tongue
weight rating (600# vs. 500#) compared to the Pilot, Passport, Highlander, and other passenger SUVs in the same class. That would be a good thing for a 17’
Casita, which typically runs heavy on the tongue. AWD is required for the 5000/600# rating.
Seems like a decent combination to me, assuming you won’t be traveling with too many people or too much gear, which reduces towing capacity. Hill-climbing will be adequate, but not like a full-sized V8 or Ecoboost truck.
Which transmission do you have?
