Towing courses

Because of a medical condition my OH is now not allowed to drive for the next 12 months.  This means that next year, it is down to me to tow the van.  I do tow the van, on long journeys we have always shared the task.  However, I don't class myself as fully experienced.  As next year I won't be able to handover to my husband to do "difficult" manoeuvres, I think I would benefit from a towing course.  But, which should I choose, the 2 day cover everything one, or the one day manoeuvring one.  It is the reversing that I am least confident in,   I am inclined towards the 2 day course as I guess it wouldn't hurt to have instruction in all the other bits as well.  What would other posters opt for?  And has anyone been on one of these courses in recent times?  Hubby did one in 1987!
