I reckon you could manage SS if you were geared low and didn't have any long uphill grinds around. The momentum tends to punch you most of the way up short, sharp stuff, and it's a light trailer anyway.
Harold - recumbent trike or upright? Definitely agree with gears on laid down stuff, but then you haven't got the option of putting your body weight through the pedals.
