OK I didn't read the whole thread, read a few pages and skipped to the end. Bet heres my opinion on chains.
I think they are great. I run a full size thats usually right around 7500-8500 and when your that heavy it real tough to make em float. If chains weren't great why do all municipalities and counties that have to push or move any amount of snow run em an not a good siped tire?
Any who, I got a set of heavy truck chains that I cut to fit, I don't run any tensioners or anything. I just air down a pair of tires slide em on and air em up.
As far as storage goes, most people carry a spare outside the vehicle on a swing out why not drape em over that? Most people also have a big after market bumper you could hang em on too, that would also up the "cool" factor a few notches also. If you run 2 spares just put em on the tires ready to go, its much easier to change tires than it is to install chains when your already stuck.
Couple pics, This was a storm we got 2 years ago. We had already had about 14" of snow when this storm dumped about a foot more but with high wind and drifted everything shut.
This first set was with 4" of lift and 35" BFG ATs and I was STUCK hard
The next day I dug the 34" swampers out and fit the chains
On my way over to a buddys to pull him out I ran into a road that had drifted closed again and with out the chains on some wheel speed and plenty of HP I would have been walking. about 300 yds past this photo op I busted out to see a toyota car geting pushed out of the ditch after turning around after seeing the road. The look on their faces was priceless when they saw me bust out of the great white unknown. I'm not gonna lie it took some trying to get busted all the way through but it made it all the way under it own power.
Heres the truck I had to drag out to the road. About 15,000lbs of loaded car hauler
