So a Short rope works ok for one sled? Doesn't the sled run into the Snowmobile or AT when you stop? I guess if you are going slow enough just before stopping it would work.
To elaborate on how I run the ropes:
I'm usually pulling a clam scout and a clam pro. I'll put a carabiner on the stock pull rope of the pro and hook that carabiner to the hitch of the snomobile. Then I'll take a long braided rope with a carabiner on each end, one carabiner hooked to the pull rope of the scout and the other carabiner hooked to the snomobile. Just need to make sure the rope is long enough to get the second sled a couple feet behind the first sled. Just be sure to take off and slow down slowly. Be smart and there's no problem, never had a single issue pulling houses this way.
I've used tow bars as well but I've been just using ropes for over 5 years now. Not because I'm cheap or lazy, but because I like to move spots a lot and hole hope with my house, that's the point of using small 1 man houses... mobility. And having a tow bar on there just didn't do it for me.
As mentioned in my earlier post, I do this for lake travel. I didn't notice the OP was wanting to use it snowmobile trails, that's my bad. If the trail is narrow, hilly, or lots of sharp turns... I would recommend a rigid tow bar for sure. But if it's a straight trail or lake travel, no way am I using a tow bar.
