I passed in Dec 95, which means i also have C1+E & D1+E, this is printed on the back of the photo license.
Direct.Gov website states:
'All drivers who passed a car test before 1 January 1997 retain their existing entitlement to tow trailers until their licence expires'

Just check the codes on your license (bk of photo section).
unless you have hgv you can only tow a camping trailer upto 750 kg on 7.5 ton lorry as you have 107 restriction 8250kg.
but can tow a 3500kg trailer on smailer vehicle, several people have been done for it.
