Well.....I've gone full circle and am now back to using our 18" Southwest Disk for our camp cooking. I just prefer the larger cooking zone and better heat control provided by the burner. I tried using the Skottle exclusively for several camping trips this year but it's just not the optimum solution for us. Our situation is a little different now that we have a travel trailer and 3/4-ton truck. If we were still camping out of our trail rig I'd stick it out with the Skottle due to the compactness.
There's nothing wrong with the Skottle and it's a great choice when limited on space, but we're just not in that position. I did modify the SW disk by cutting the handles off and running chain through the remaining hollow square tubing welded to the disc. I used Silicone tubing on the chain and even after cooking for extended time I feel no heat transfer to the handles, plus it gave me a good place to hang utensils from.
So the Skottle is now retired and the SW Disk(s) are used for both home and camp cooking, I feel like it's the best fit for our particular situation. I am still using the Step 22 case to carry the SW disk, lid, steam tray, 10' gas hose and all the utensils. The burner is carried separately, but still collapses down really compact and it allows us to use other pots/pans on it if we desire to so it's a much more flexible cooking option.
