How high are the mountains, what altitudes are you planning?
I'd say forget the hourly rate. What is the trip cost for each platform (since you list a 500nm leg length) ?
What are your priorities? Trip cost? Travel time? Pax comfort?
Is this a one time trip or an on-going thing?
~14,500' (Mount Whitney). Planning on 12,000' if IFR and maybe up to 14,000' on a shorter leg... lower if VFR. Obviously the 182 is going to be the cheapest.
I want to fit 3 pairs of skis, boots, poles, etc. My priorities are comfort then cost then time.
It will be an on-going thing.
Ship the skis and boots.
For 14,000, your bumping the max altitude for a normally aspirated 210/182RG.
Mission profile: 3 pax @ 250lbs per, 500nm, 7,000' airport elevation, 6,000' long runway, majority of flight over/near mountainous terrain
C-182T or RG - $185
C-210L - $210
SR-22 - $280
BE-76 - $220
Theres a 210 right now on TAP with a ski pod under the belly. That has to be the only 210 I've ever seen with one.
Cessna 210D service ceiling is 21k feet, no turbo.

+1 for the Duchess. It's as comfortable as a C210, it's a very sweet flier, and let's face it, assuming you live past the climb to 1000' agl it's safer.
Especially over mountains where your off field landing options (wheels, belly, or parachute) are much more restricted compared to say, Kansas.
Single engine service ceiling on the Duchess will not clear tall rocks, and doubles your probability of an engine failure.
I'd go twin anyway because iFlyTwins, but I would call it a wash at best for that area. Probably worse than a wash.
Assuming in either the 210 or the Dutchess; the engine goes out you turn away from the peaks and go down hill to find the next airport, wouldn't the 2nd fan help you go farther?
Is the decent slower in a twin with one fan than in a single with no power?

That would be the theoretical benefit, and there will be a lot of variables that go into it. It might make sense depending on where you're flying, but over the big rocks I tend to think it's a crap shoot at best.
I'll argue safety benefits of twins in many cases, my point is that's not one.
And yet when you visit airports in those areas the mix of planes looks very similar to that in flatland areas. What do they know that we don't?
One advantage of the Dutchess is that she has two very reliable O-360 motors, which in my unscientific opinion are significantly less likely to fail than the higher power motors in the other choices.
That is a good point. Two O-360s do have twice the probability of failing of one O-360, but probably less than twice the probability vs. an IO-520.
Winter conditions in the Rockies range from O/0 in snow and ice to 'Clear and a Million'. Stay on the ground for the IMC and fly in the CAVU and all is fine.
Which is great, but OP's not flying the Rockies; they are doing SD-Mt Whitney (Sierras).
That Duchess had better be in TERRIFIC shape at $220K, it's a trainer.....
