Blackbear will be tight. May be doable. Once you get to the steps, you’re committed. You’ll have to make a 20-pt turn at the switchbacks due to your length and width. I took my DCSB Tacoma and I wouldn’t want to take anything longer or wider. But just depends on your comfort level of skirting the edges.I'll assume you've tried because I see you have a DC yourself, but I had talked to a few different people with first gen DCs who said it was doable, just a little tight in the switchbacks. It's going to be a real bummer if I can't, that's the one trail I've been wanting to do the longest.
Your rear bumper will get hung up. I recommend some sort of protection back there. I used this, which worked great.
