The Ridgeline is a car-based SUV with a pickup truck-like bed. It's an excellent vehicle, and capable of towing what it's rated to tow at the speeds it's rated to tow it (55-60 mph). When reading comments from people who had them in the past - keep in mind that prior to the 2009 it was under-powered, had severe limitations on the tow recommendations, and Honda had issues with the transmission when used for towing.
They redesigned it (and the Pilot and Odyssey - the other vehicles built on the same platform) for 2009 and it's been quite good since then. The new 9-speed introduced for the 2016 model year seems to need a little work yet - I'd get the 6-speed if getting one of the three vehicles new.
