Ifor Williams 505 with my BMW 320d tourer - with factory fitted tow bar and adjusted suspension - but only tow one 350kg pony! Need to buy a four by four so I can tow 16 TB as well.
I used to tow a rice trailer with a Diahatsui Fourtrak, then I had an Ifor 510 it managed both fine until the Ifor was stolen and a huge oil leak started on the 4trak. Now I am towing the rice again with a 3L Nissan Terrano. I did get an Iveco 7.5T but my Shire cross is very long in the body and has to stand at an angle taking up 2 stalls and it seems too big for the ponies (12'2 and 13'2) so I am going to sell it and get another Ifor 510.
