Towards the end of the criminally neglected 1970s weepie Love and Pain and the Whole Damn Thing, a terminally ill Maggie Smith and her young lover escape for a romantic getaway on the then-deserted Spanish costa in the cosiest and tiniest of caravans you have ever seen (towed, apparently, by a 2CV).

I hope Hollywood never gets around to doing a remake of the film. But if they do, they wouldn’t go far wrong in using as a modern alternative the smallest model in the six-strong Caravelair range that Marquis Leisure has just introduced to its network.

The two-berth Caravelair Antarès 335 has a MiRO of just 726kg. Marquis hopes that the low weight will appeal to the first-time buyers it believes are the key market for this entry-level van, because there will be no need for them to upgrade their tow car.

They could opt almost as easily for any of the other caravans in the range – the two/four-berth 420, the three-berth 450, the four-berth 455, the four/six-berth 476, or the six/seven-berth 496. None of them has an MTPLM figure that’s higher than 1300kg.

The Caravelair Antarès 335 is currently on offer for just £11,995 (a price that includes an air awning and starter pack thrown in), making it equally easy on the wallet. The most expensive model in the range, the 496, still comes in five pounds short of £15,000.

That figure is becoming an increasingly rare occurance, as Practical Caravan found when it came to judging the budget category of our Tourer of the Year Awards, where the cut-off point is £15,000.

Still, does such a tempting proposition work out in the real world? Does the 335 make an affordable, practical proposition for a cosy weekend away for just the two of you?
