Bateson Deauville, well built, loads of head room, light inside, tows well, doesn't rattle. I towed my 16h2" without any issue. Oh, the off ramp also opens on the nearside so if anything happens you can offload onto the verge rather than into traffic like many of the older Ifors etc. They also hold their value.
Bateson Ascot (if you can find one). Tows like a dream,roomy, very quiet, tack locker in the front so you don't mess up your car and nicely put together. Love mine!
