We have a camper van, an Autosleeper Rambler on a Talbot Express base and wouldn't be without it. Apart from having to make sure everything is locked down before you drive off, that outweighs all else. Central heating for cold winters, late autumns and early springs, running hot water when you wake up, your own toilet and shower..... We always take a small awning with us which is useful for keeping wet clothes in or having that extra bit of space if you are away for any length of time. Disadvantages, not being able to drive off , but, most sites let you put your number plate up, so your space is there when you get back and if you have your awning up you just leave it up and hitch back up when you get back. Make sure you get one with power steering which means you can turn them on a sixpence and they are incredibly easy to manouevre. Watch out for height boards! Have fun.
