welcome to FRF!
as someone who almost bought a Ridgeline for a tow vehicle, i strongly suggest you do lots of research.
we ended up eliminating it from our choices, mainly because of Honda's anti-WDH recommendation and its 5000lbs. towing capacity, even though we both really loved it.
any company that doesn't recommend using a WDH for towing, is saying that it's not a competent tow vehicle. as far as i know, Honda is the only auto company that has this policy. to me it says, we don't trust our vehicles to tow anything but a boat or popup.
i know that there's a Ridgeline Owner's forum on the internet. you might want to do some research there.
