What sort of camping are we talking about, arrive at a campsite, take the tent out of the boot of the car and depending on the tent, 5 - 25 minutes later you have your portable house ready to live in, while pitching the tent, have the pump plugged into the car cigarette lighter and your bed is ready to place in your sleeping room, get the seats out and relax while your burgers fry on the two ring gas burner and take a cool can of cider out of the cool bag, if the weather gets a bit chilly then turn on the stove of better still the camping heater, soon warms the tent up.
If you have a tent bigger than the amount of people, then place the portaloo in the spare room, if not then place it under a tarp outside the tent, no shitting in a field.
Or, if you prefer just getting a couple of tarps, 4 bungee cords, a kerri mat, a sleeping bag and go exploring the wonderful wild scenery this country has to offer, again great experiences.
Far better than towing a rigid portable garden shed behind you, or stopping in a house where some chav has "taken" his chavette the night before, or wasting good beer tokens in some yuppy establishment where asking for a pint gets you derided especially when you see the price.
Nah, a field, a tent, good company, and a cool bag full of cider (and some scoff), and i can really relax.
