I've found the diamond chains to be easiest to put on. Traction like a link, install like a cable. Don;t generally speaking have to lay out chains, drive on them, hook up. Can do all the above in one place. ALL versions one should drive a few hundred yards, check tension, then do so every so often to make sure they are tight. Otherwise as noted, if too loose, they fall off, tear up the rig etc.
From Nov 1 to April 1, ALL rigs over a total of 10K lbs, be it a single rig, or towing, are required to carry the appropriate quantity of chains for the rig in Washington state.
I would suggest a chain you know will work, as you can not always trust mother nature, or your days of travel! You may get caught in a freak snow storm, and your ability to wait it out is not legal, or no place to truly wait it out. I was at Timberline in the parking lot, a place I have stayed and been many times in the winter, 60 mph winds, blowing snow into every nook and cranny of window vents etc. Put chains on truck and trainer, down that 10% grade I went to Government camp, spent the rest of the weekend in a parking lot down there. If traveling in the winter, be safe over sorry. Putting on chains is not that big a deal.
This is from a person that used my RV trailer as a ski hut, not a summmer vacation traveling home! Hence the license plate I had too "SKIHT46" or truck plate, see handle!
