A 182 can work on skis fine, with some judgement and common sense applied.
I knew a fellow who ran one on straight skis for a number of writers.
As always, pure straight skis are going to be the best performers. So, if your situation permits the use of straight skis, I’d definitely go there.
Penetration skis add some weight, and drag, due to tires sticking down through the skis, so drag can be substantial. The type and depth of snow you’ll encounter will determine how well such a rig will work.
Retractable skis are great, but as you noted, they’re heavy. I’m not familiar with Kehler skis, so can’t offer much advice. But retractable skis on a tri gear are apt to add up to ~200 pounds to the basic weight. That’s a lot.
At one point, our outfit rigged a 206 with retractable mains and a penetration nose ski. I got volunteered to give it a test flight. That was a VERY bad setup. That nose ski had the wheel attach point a little bit aft of center. In deep snow, ANY rudder deflection would cause that nose ski to go instantly hard over to the limit. I had a hell of a time getting a runway stamped down and figuring out how to keep that nose ski straight for takeoff.
Got back to town and told mechanics that they were welcome to fly the thing any time, but not to call me to rescue them.
A fellow in Fairbanks trapped with a 206 on retractables.....I can’t recall for sure, but I think they were Fly Lite 4000 mains and a Fly Lite 3000 nose ski, though that nose ski was likely designed as a nose ski. That ski had more ski aft of the axle than in front. He went just about everyplace in that thing, and performance was great.
I’m not familiar with any ski approvals for the 182, but the STC for the 206 lowers the gross weight substantially, to the point where useful load was pretty low. If I recall, gross was limited to 3350?? I never learned why that limitation, but assumed it was nose gear related.
I’d check that on any 182 approval before I leaped.
