I have the equivalent to the Alhambra, the VW Sharan with the 115bhp diesel. I tow a Coachman Amara 550/5, a heavy van, 21 ft long, with all the usuals for a family of 4: awning, groundsheet, garden chair and table, microwave, water stuff, clothes food etc.
I haven't been touring for long, since Feb 07 actually, but recently I went all the way down to Pembroke, 200 miles, mway, a roads, b roads, steep hills, etc - absolutley no problem what so-ever. I would be surprsed if you had a problem with the 110bhp version also.
I spoke to a friend who works for Ford, his job is to test engines to determine the best map, when I spoke to him about changing my engine map to increase the hp, he couldn't see the point considering what I already had.
Stability, excellent, I was overtaking HGVs on the mway, up to 65mph - no problem. I was overtaken by coaches - no problem.
Load space - cavernous. We take out the rear 2 two seats when we go away, and all of the awning including poles, groundsheet chairs, table, supplies, all fit without any probs.
