Hi Graeme. Yes mine is 193 bhp. I think you did well to get 18 mpg with 5 adults and a fully laden caravan! My figures are for two only, fairly lightly loaded with no awning and I do drive gently. I did have a problem with a lack of power this year, which turned out to be a faulty mass air flow meter (which tells the engine management computer how much diesel to squirt in). However, this was a dramatic lack of power and I don't think your car has a problem, although it (and the turbo) is quite a common problem with this model. I usually select sports mode when towing as this holds in 4th gear (5th is not selected) and also increases the revs before the gears change. I change back to drive mode on autoroutes and often use manual selection on hilly routes. I do this out of respect for the car, recognising that it was not really built for towing.
