While in the Black canyon area, leave your trailer at a park and drive up Hwy 50 towards Gunnison and take CO Hwy 92(Scenic Byway) towards Hotchkiss. You'll get some awesome views of the upper Black Canyon you won't see from the other side. It's a beautiful drive up through the Gunnison National Forest. You can go to Hotchkiss, Delta, and end up back in Montrose.
If you take your trailer, you will have some steep grades and sharp turns, negotiable with your trailer, but will work your truck. I pulled a 29' 5th wheel over the road--no problems. There is a very nice Colorado State Park at Crawford.
Another very scenic drive is CO Hwy 65 from Delta up to Grand Mesa. Spectacular views from the top of Grand Mesa.
Enjoy you trip to Colorado, my "adopted home state".
