Been getting ready also found some killer chains in grampas barn, got em cut size now gotta fit them up. Had an old phone holder in big rig I made a bracket for handle bars for iPhone-navionics will try and get a pic up when done. What's the pros and cons with carrying shanty piggy back versus towing???keep up the good work guys 
Cons for draging are:
you have to travel slower
usually have to drag across bridges over pressure cracks
bumpy ice raises hell with anything in your shack
if your using a rope to pull shack it swings all over on bare ice
snow / slush from tires gets thrown onto/in shack if its close to back of wheeler (as in fixed hitch)
Pros for piggy back are:
faster travel
suspension lessens bumpy ice issues in shack
no tire spay on shack
shack can be left on the wheeler traveling to/from fishing spot
no issue backing up if needed
Last winter when there was slush on the ice it was getting kicked back on my shack and if I did not have the cover on it was a terrible mess inside the tub, I really hope this works out.
