4. There are two ways to put on chains: a) drive onto them and fasten them at the top, and b) put them on from the top and fasten at the bottom. I've done both ways but find the top-down approach is easier as gravity is working with you.
Carry a couple 6" 2x4s. Drive up on them before chaining (unless you can't move). That will give you a lot more adjusting clearance.
I lay the chains out in front of the tires and put the blocks between the rails about 2 cross links from the end. Drive up on them then pull the chains over the tires. That puts the latches where you can get at them easier.
