I like the Colorado diesel but gotta say that the latest Ridgeline is better in just about every respect besides towing and torque (heck, it even has a higher rated bed weight capacity). If the Colorado did not have the diesel option than by no means would it stand much of a chance vs the Ridgeline! If it were not for the diesel option most of us here would not have bought the Colorado/Canyon, right? And if the 4 AWD Ridgeline was rated with an extra 2 to 3 thousand lbs towing than it would have been that much easier for us to choose it over the Colorado/Canyon diesel, I think. Not to mention Honda has better customer service and quality reputation than Chevy/GMC. But I am glad GMC took a chance and introduced the 2.8L LWN powerplant, that is the only reason the Colorado/Canyon can even compete vs the Ridgeline

. Sure the Ridgeline is a few inches lower to the ground and its body structure is different than the typical pickup truck frame setup that's been around for generations and that it can't tow as much, but it still accomplishes the basics that defines a pickup. That is, to be able to tow a reasonable load, have at least rear wheel drive, have an open bed, and be able to handle rough dirt roads (I'm not talking about trails with foot high bolder protruding and ridiculous inclines, since most dirt roads that lead somewhere worthwhile are not going to be that bad).
I just hope the baby Duramax diesel and its transmission turns out to be reliably engineered&manufactured, else I'm going to be called out for it down the road and my reputation for advice will hit rock bottom
Having said all that, I ended up recommending the Colorado Diesel to my dad, not the Ridgeline, because of two things: better towing (essential for what he will be doing) and torque (diesel perk)...And guess witch one he opted for? Yup the diesel Colorado ! ! !
