I have loops spliced into my line (and will on future lines as well), I just put the loop into the receiver and put the pin through it. Noted that it has abbrassion/angle potential, but I'll inspect lines and cover them as needed.

Being in a small car, I have relativly limited storage. I could put things on top of my storage area in the hatch back area, but the more I have there the more likely I am to take it out when I'm going on a road trip, etc (for space) and thus less likely to have it when I need it.

Since I own a Jeep that I've built for serious offroading, I keep the following in it:

30'long 3" wide 30,000 pound rated snatch strap
8' long 3" wide 30,000 pound "tree saver" strap
20' heavy duty tow truck chain
receiver hitch-mounted shackle bracket
beefy front tow hooks mounted directly to the frame
a few 3/4" D-rings
a snatch block
a 48" Hi-Lift jack

That's pretty much all my recovery-type gear.

I fried my winch one day and need to buy another one (burnt up the solenoid pack AND the motor), but I should be good until I lay hands on another one.

I use Spectra/Dyneema string for flying kites. It that use, it is known for very low stretch and being very slippery. Both desireable for stunt kite flying. But because it is so slippery it does not hold knots well (that's an understatement!) You "sleeve" it where you need to tie knots. You thread it through an external sleeve (similar to the covering over the 7 strands inside paracord), and then tie your knot in this added sleeving.

I should never have to tie knots in it, as I've spliced in the loops featured in the photos. That said, we do tie knots in dyneema sailing. Usually just a bowline. I wouldn't trust my life to it, but it hasn't failed on a spin sheet while I've been on board. That said, it is smaller strand than my towline, so that may help w/knot holding.

+1 on that. Never use the ball as a recovery point. Aside from the risk of tearing it off the vehicle, you'll find it's very hard to keep the strap from slipping off. If you don't have a hard-mounted recovery point, wrap the strap around the hitch receiver frame, or get one of those hitch recovery shackles (they're only about $50, IIRC). Hint: stick a rag, extra gloves, sticks, whatever in the loop as they can tighten-up pretty good and be difficult to get apart.

Be careful with that... I have not done much in the way of recovery work since we rarely get deep snow here, but I have spent time reading over the years to know what to buy for my equipment. Using the pin in a receiver this way can be iffy since it is meant to hold a hitch or similar gadget in place rather than a rope or strap. It is designed to not simply shear off when tension is applied to the hitch, but it will not necessarily resist bending when tension is applied to a small point on it (like a rope).

I originally had the same idea as you, but after looking into it I spent the $40 on a receiver shackle bracket instead.

EDIT: May as well list my stuff too; you should all feel free to tell me if I'm being stupid:

25' 20,000 pound recovery strap with loops on both ends.
15' chain
2-ton come-along
Receiver shackle bracket with 2 3/4" shackles
8' nylon tow rope with hooks that came with a roadside emergency kit (can't see me using this for much of anything)

YOur list looks good, the 2ton come-along may be a good helper if you have to get over a smaller object or just give asstance to your vehicle in a time of need.

As for the 8' nylon tow rope with hooks. With all the gear that I have, I hate to admit it, I have had to use one of those hooks as it was the best hook to connect to a car I was pulling out.

so while you may wonder why you have that cheep POS tow rope, there may be a day that the hooks come in realy handy. Speaking of atachments, the loops on the recovery strap may need shackels for pulling or attaching to the front of trucks/vehicles.

Keep in mind that Ford uses totaly closed tow hooks, they are just loops on the front of the truck.. To add to the fun the material of the loop is HUGE and you need a 6ton shackle to get around the material of the loop.

You can never have too much recovery gear.
