we've been caravanning for more years than i care to think about and really love the life-style. we started out when our two kids were 5 and 7 and we had some great holoidays. we're retired now and spend about 12 weeks in europe in it, not to mention all the time here in britain too. it's a bit like marmite - you either love it or hate it, and i think there's still a perception by some that it's very basic. well our caravan has all mod cons - central heating, shower, running hot and cold water, a flush loo, a 4 ring cooker and oven, large fridge, very comfy bed with sprung mattress - it's like taking your own apartment/house away with you.
i would advise you to join a forum where you'll get lots of info and advice on all aspects of caravanning, people are really happy to share their knowledge. and you'll find lots of help on sites too, when you turn up for the first time and aren't sure what to do. we're members of 4 forums but by far the best is caravan talk:
