I've had a Clam Kenai for several years and I absolutely love it 95% of the time, but I know it's not for everyone. I usually pull it with my SxS that has a plow in the front, and when I get to the spot I'm looking for, I put the plow down move the snow and then park the sled on a cleared spot in one quick moment.
Floor space wise, I have a hole on the left that is closer to me that I use for jigging, and the hole on the right further away from me for dead stick / bobber (but still close enough if I want to Jig with that). I have the flasher dropped in the right hole and I can almost always see both baits, even if I'm pan fishing. When I have my camera going, I drill a 3rd hole right by my sled in the middle so it's out of the way, rarely get tangled when fighting a fish. With this setup, it's super easy to just walk out through the middle if I need to leave the house through the front door. I usually don't use the door, I just flip back.
I have the smaller Buddy heater in the left corner. I'm often fishing in jeans and a t-shirt.
It pulls just fine behind a 4-wheeler, a SxS and a sled (some people think it pulls real hard with a sled, I don't.....but it sucks pulling by hand). It's honestly not that light where it's super easy to throw in the back of a back of a pickup...and that's the 5% of the time I hate it. I really don't think you save that much in weight or space if you get a two small man. I like the efficiency of the Kenai, and it's 100% based on how I like to fish.
