I almost always go for Hardstanding when I take the Eriba away,
after trying screw in pegs and other types, I tend to use
Blue Diamond Rock Pegs around £10 for 20 pegs in a case.
I also use the 10" Heavy Duty Green Topped Rock Pegs which
are often sold in the site shops. For the storm strap the
rebar type Marquee Spikes are really good.

On grass I like the Sampson range of tent pegs, triangular with
a welded in bar hook, or the tough plastic pegs.
Wire pegs go in easier but also come out easily when you don't
want them to!
If you have to use wire pegs, try double pegging, using a short 15"
length of guy rope with a loop at each end. Attach it to the original
guy and peg then stretch it out and put in a second peg through
the remaining loop.
On my Porch and Awning, I use internal guys pegged from the
front corners, inside, across the frame at 45deg. a sort of belt
and bracers approach.

I use what ever is in my collection, mostly steel stuff.

No idea what they are called but I bought some that look like chrome plated 8" nails.

A claw hammer is a must for any eventuality!

nowt like a good hammer plus socket set, spanners, wrecking bar, string, ree bar think gone slightly over top

The Claw Hammer is good for knocking rock pegs in, then use
the claw part for pulling them out. Not over the top at all.

Hiya when camping I used delta pegs metal ones both on hard and soft locations. I intend to use them with the awning and porch but as I have not had chance to go anywhere yet since I have had the Puck never mind put the porch or awning up. These are cracking pegs and lay flat with the ground when put in right brilliant when there are children running around. They are also really good anchors never had one pull out since using them expensive but as always you get what you pay for.
Morphy.

I am using the composite, Peggy Pegs, a bit on the expensive side, but apart from extreme cases where a masonry bit has been employed, have coped really well.
PS if you have a wind out awning, Peggy Pegs do a great , quick-release mount for the legs which allows you to use 4 screws to hold each leg down and releasing it in seconds, if you need to wind it in, in an emergency.
Still doesn't stop me taking a peg box containing samples of every other peg on the market, us chaps can never have too many pegs!!!

You are definitely a Chap, Randa,.....We buy the shiniest, bestest new kit as soon as it hits the shops, but we get the last ounce of use out of the old stuff before dirtying it,....We're Chaps,..it's what we do!

Pegs pegs I got loads of pegs long pegs wire pegs rock pegs clothes pegs tooth pegs you name it I got it

A 1lb lump hammer and a leather glove when Im knocking in the rock pegs, I could do with a swear box when I miss as well

I watched "Oceans 13" the other night, now I want one of those guns they used to fire the anchoring bolts into the concrete of the skyscraper to lift that diamond display cabinet with the helo.
On second thoughts, even that might struggle with some Caravan Club hardstandings,...

Blimey - is there a campsite by the name of OK Corral around your way where everybody walks around with holsters on their hips that are either festooned with bolt or nail firing guns? I'd be there in a jiffy if only I could find my Stetson.
