My partner passed her test before 1997 but i didnt pass mine until after

Ive read all my licence conditions but what a palarva!!!!
The dvla website says this,
Vehicles you can drive and how old you must be to drive them
The tables list the vehicle category descriptions for driving tests passed after 1 January 1997 and the minimum ages for driving them. All weights refer to maximum authorised mass (MAM) unless stated otherwise. This is the total weight of the vehicle plus the maximum load it can carry
vehicle B
Motor vehicles with a MAM not exceeding 3500kg having not more than eight passenger seats with a trailer up to 750kg. Combinations of towing vehicles in category B and a trailer, where the MAM of the combination does not exceed 3500kg and the MAM of the trailer does not exceed the unladen mass of the towing
What does it all mean?
Any ideas?
Were only thinking of getting a lightweight caravan,i really want to get an eriba puck shes looking at something a bit bigger but not much bigger but im not sure if i can tow a caravan at all on my licence?
Granted she can but we want to share the driving,so if anybody out there who passed after 1997 has towed a caravan we would be grateful for your advise?
it appears i can tow upto 750kg an eriba puck is under that but then it states something about the combined weight being no more than 3500kg so if for instance the car is 1800 does that mean i can tow something over 750kg so long as the combined weight isnt over 3500kg?
its soo soo confusing!!!!!

also it mentions laden weight for car but is the 750kg for trailer laden or unladen?
Any advise would be gratefully appeciated
