Difficulty of some CO routes?

As to the diesel justification, we bought a Tundra with the 9,500 tow package to pull a 7,600 lb trailer in early 2013. I've had a diesel before, and very much did not want a diesel again. I'm a relative newbie, and I also have everything set up around 80-85% of limits.

16 months after we bought this we did a 4,500 mile trip from Ala to Utah, and just got back late June from a 3,600 mile trip to Montrose and Colorado Springs, CO.

The gas Tundra has done everything we have asked it to do, including pulling the trailer over Monarch Pass (11,300 feet) 4 weeks ago (also North Pass and Raton Pass). We never get below 50 MPH or over 4,500 RPM going up anything we've been across so far. It was actually more of a challenge going down those mountains than up --- you have to set a strategy to use the brakes as little as possible. It probably took us twice as long to go down Monarch Pass as going up, but we did not create a traffic jam -- every other RV and big truck was doing the same thing. Low gear is your friend on the other side of the hill.

We get passed by a lot of diesels going up the hills, but that's ok. Our gas truck is quiet and smooth and gets about 9 MPG here in the SE where there aren't headwinds and tailwinds. Solo it will push 20 MPG on a trip.

We found the Mountain Directory for Truckers to be very informative. I bought both the east and west directories. I planned our route around the west version, and used the east version as a reference point for grades we have traveled here in the South.

Take your time and don't push the truck and you will be fine. You can always justify the diesel to the boss on extended range, bigger trailer, or faster trips if that is what you want.

My last trip with my half-ton Suburban pulling a ~6,000-lb trailer was to Yellowstone and Colorado. It was my last trip because soon after I bought my 3/4-ton Suburban.

We went over Powder River Pass in Wyoming - elevation 9,666 feet. My half-ton had the 5.3 engine, 4-speed auto transmission, and 4.10 gears. Best we could manage up the last few hills was 25 MPH in first gear. Fortunately, it was late in the afternoon, so traffic was light and there were very few cars on the road to get mad at us.

Going down was fine - I let the transmission and the engine do all the work. My brakes weren't even warm after the descent.

Was I stressed? No. However, I lived in Colorado for 10 years (plenty of experience driving in the mountains), and I'm also a seasoned road warrior, so I'm used to that kind of thing. Someone with less experience probably would not have fared as well.

For your western travels you might want to purchase 'The Mountain Directory for RVers and Truckers - West Edition'. Even though we absolutely love mountain driving we always refreshed ourselves on the routes.

Purchase it from the publishers, not from Amazon which is extremely expensive for some reason. It's should cost you about $22.

"I understand many of you are much more experienced than we are, so I'd appreciate answers from the perspective of a rookie, rather than a grizzled veteran"

As a rookie going down Wolf Creek Pass your first time, you need to use the slow down by down shifting technique. If you rely on your brakes all the way down, you won't have any brakes at the bottom.

Looks to me like any of those routes are doable for you. Pueblo to BV via 50 and 24 is one I can verify as I've towed a 33' fiver on that route with no issue. Remember that CO is flush with RV's and you never hear of anyone really getting stuck in a situation unless they go on a 4WD trail over a 14000' peak. Very rare. Stick to a main road and you'll do fine. I would avoid Independence pass in anything longer than a Lincoln Continental is my only caveat.

Well, we want to do this east-south CO trip this summer, and then next year we want to do TX-west CO-Yellowstone/Grand Tetons-Glacier NP-Black Hills/Badlands SD-back home over the course of 6 weeks or so.

That's a lot of towing and in the mountains. So it has me thinking. I want a safe, enjoyable experience. If my current truck will provide that, that's my preference. On the other hand, if it won't (or can do it, but will rag the truck out), better to explore my options now while it's a year away.

Those are all paved highways, therefore not difficult.
The difficult ones are not paved and one lane wide.

Yes, I hasten to say that I always take the Cotapaxi cut off. I was just keeping my comment general about the road. I agree completely.

Pueblo to Buena Vista (three routes shown here... best one?)

I wouldn't necessarily take any of the three. I'd head south to Poncha Springs, then east on US 50 all the way to Pueblo.

I agree with taking CO 69 instead of 96 if you choose to go through Westcliffe. Hardscrabble Canyon on 96 is pretty steep and windy. If you do take the route through Westcliffe, keep an eye out for the turn onto CO Rd 1A. There's a sign saying Cotopaxi 7 and that's where you'll turn. (I make this drive four or five times a year.) If you're coming the other from Salida, the turn isn't obvious until you're right on it. It's just past the liquor store and just before the Cotopaxi Store.

As far as four lane roads, even US 50 is two lane most of the way, as are big stretches of the other roads you've asked about.
