you may need a long drop plate to get the ball height correct. Some companies do a removable one so that it doesn't become aplough offroad.
otherwise i would say the same advice as driving any other lifted vehicle on road- its taller and bouncier so go slower and be more careful.

What year is it? Makes a difference, past a certain year tow bars need to be type approved and marked as such. Most towbars are NOT type approved with the use of a drop plate, although many 4x4 ones are. It will be a particular size, though, ie the manufacturer will have put it through testing at stock height and with (for example) a 4" drop plate. So you can't just bolt up a 6" drop plate and be legal.
If its before the year requirement (I think from vague memory its 1 april 1997) then there's no such red tape and you can use a drop plate with no worries. Except that if its too long, its likely to bend under the constant forces applied, so if you can get it braced at the top through 2 pairs of bolt holes, or at the bottom, then it makes good engineering sense.

Thanks for the info its a 95 discovery drop plate sounds like the way forward.
I drive it like a bit of an old man to be honest never over 55-60mph usually 55 its just not worth it. My grandad has a saying "your better being a few minutes late in this life than several years early in the next".

I swan necked the draw bar on my trailer. Keeps the trailer level and works just fine.
Would depend on what exactly you're towing though!

Just to clarify the date - Any light passenger vehicle registered in the UK on or after August 1st 1998 ('S' Registration) will require a type approved towbar and towball (when fitted).

Standard tow ball height is 350-420mm. The lower the tow ball, the more stable at towing the combination will become. If you can get the tow ball height below the height of the hubs (around 393mm with 31" tyres) then it gives you massive stability advantages which means heavy trailers are more towable.
Cheers for the date clarification - my vague memory!

i have a discovery with a 3 inch lift. it has a standard land rover tow pack on it which i use really for recovery. Even that is bit of a plough and its a lot higher than a tow ball should be. i have towed with it a couple of times and it tends to make the end of the trailer get a bit close to the ground but it depends how much over hang you have and how many axles the trailer has. it can overload the rear trailer axle if you have too much weight on it. I once made a lowering plate out of a piece of U beam. I wouldnt reccomend it for highway use!

Apparently towbars are now becoming part of the MOT procedure, so need to be factory made or type approved & certified/stamped!

Yes except they don't need to have type approval markings, its just a basic check to see they're not corroded and are secure. They can't remove covers! So if you have a tow ball cover, they aren't allowed to remove it to check the condition of the ball. Crazy but true. And they don't check the electrics either.
