I have one of those 3 burner type bbq/stove type of things. (everyone has seen them, either 2 or 3 burners, lid folds back and side windbreaks fold out). I have a stand that it sits on to use, just chrome wire type thing so it is free standing and not taking any bench space from you.
Couple one of these with the cast iron hotplate to suit and they are very handy indeed.
The main advantage of this is you can lift off the hotplate and use the burners just like the stove top at home.
Fold down quite small, add a gas bottle and take anywhere.
It does have its limitations, like its size. If you are cooking for more than 2 or 3 it seems a bit on the small size and you have to cook some things, then take them off and cook some more things.
I have been using one of these for a week at a time 2 or 3 times a year for the last 15 years.
