I tow a 1300kg with the 'old' model 2ltr diesel Santy. For this weight of van it's a great towcar, stable, pulls well, lots of room & useful on wet fields & farm tracks. Possibly for a heavier van in the 1450-1500kg range it would struggle a bit though, particularly uphill & m/way inclines.It would still pull your van but might make heavy weather of it.
