BBQ

We have a cadac safari chef, there are only two of us so it is quite big enough. you can buy accessories if you want more than a grillplate or  bbq rack ,  and the lid can be used as a wok. it also packs away very neatly

We also use a cadac. we bought ours from amazon including all accessories for the same price as the basic set at our local caravan shop. 

Isn't a BBQ a cooker which heats food with a naked flame, onto which the food/ fat drips causing an infusion of smoke. And isn't a Cadac a hotplate, such as as might be used in McDonalds? The taste of the cooked food is entirely different. (Yes I know that Cadac have a direct cooking grid option, which leaves the stove so difficult to clean that it's very unlikely to be used twice). For world class BBQing, you could invest in an excellent but expensive and heavy Weber. People speak highly of the Cob, but I don't have experience of them myself.

I would also say Webper specifically.  The small Q series.  Expensive yes, heavy fairly although this seasons models seem to be lighter, I'm not sure this is a go thing.   You can sometimes pick up a bargain if you can wait until autumn but should last for years

The Cadac is basically a frying pan on legs so if all you want to do is cook a full English or fry a few burgers then it is fine.  

For the pedants neither the cadac or Weber Q's are barbecues, the Weber describes itself as a grill. But also calls itself the BabyQ so is aware of its use. 

I agree Jenny but I think most people refer to almost any outside cooking facility as a BBQ these days.  I do prefer charcoal myself but gas and electric gizmos have their uses.  I love my electric wok/multicooker for caravanning as well as charcoal.

We love our Cadac as it is lightweight, multi-purpose, but above all gives us meat that is succulent and better than we can achieve on a flame. We also fry eggs as part of our breakfast and have made bread using the lid. Might think twice though if we did not have an external gas point and had to carry and additional gas bottle.

We love our cadac, too. Not the same as a charcoal bbq, it's true, but light, covenient and easy to use, as well as being multi functional. We also have the paella pan, and Mr MJH is currently eyeing the smoker box...

I've said many a time a Cadac is a hot plate grill and not a BBQ. The only resemblance to a BBQ is that you use it outside. The infusion of smoke either by the introduction of smoking chips or, as Jennyc quite rightly says, by the food causing its own smokey flavour. The best BBQ I have ever had is a Weber and the range of accessories is amazing! I have the standard kettle as the accessories are amazing and the "go anywhere" BBQ which is ideal for site but I have taken the full kettle before now and some of my accessories inc the Pizza Stone! I am sure Weber do a gas version of the smaller BBQs. They also do a smoking box so gas users can have the smokey flavour too. They are not cheap but where the others just fell apart the Webers have just gone on and on. Total quality and the food you can produce is stunning! The pizzas are wonderful done on a hot stone. Try roasting a whole chicken by the 'indirect method' using the accessory side baskets- have you ever had such succulent chicken? and if you smoke it too it's sumptuous. Got to stop now- I'm dribbling on my phone!

The OP asked about gas, so although I've used a 22" charcoal Weber, their smaller Smoky Jo too, for many years I'll concentrate on their larger Q Gas BBQ which I have at home and their small Q gas which stays with the van. We also have the very portable Cadac Safari Chef for picnics and boiling kettles as well as frying onions on occasions. I bought a large Weber Q gas and the big Cadac for the charity which I worked for before I retired. Both were used frequently and successfully. Various other, and less effective, BBQs have come and gone over the years. Weber claim that you can't tell the difference between gas and charcoal on "their" BBQs due to their unique "flavouriser" bars which catch the fat, allowing it to smoke. I have to say that I tend to agree, and the smoke generated by their gas models underlines this. After all, charcoal alone is a smokeless fuel, used for just that property in smelting metal over the centuries. I regularly cook fish, shell on prawns, lobster, steaks, marinaded chicken, roast meat, vegetables, including baked potatoes, then pizzas on a tray, and pancakes on a heavy iron plate etc on our Webers. All delicious and convenient in the case of gas. I've tried the smoker box with hickory, which doesn't seem very good on gas, though hickory on charcoal works well. I use our own Cadac Safari mainly for boiling a kettle on picnics and frying onions. For culinary diversity I'd chose a Weber every time, but for an easy fry up breakfast or an additional heat source at a BBQ party, then the Cadac works well. Neither the Weber or the larger Cadac is cheap, so they don't really count in a cheaper Caravanning discussion. For a cheap solution I'd recommend the Weber Smoky Joe charcoal grill, but that's not what the OP asked about.

Whilst not strictly a BBQ, we have the Cadac-2-cook (https://www.obelink.co.uk/cadac-2-cook.html) as we rather like cooking on a hotplate / griddle outdoors (plus we wanted to keep cost and weight down). Also I am lazy, I like grills with minimal setup and cleanup etc
