Buy or hire the HL-AL 3218/27 if...
A wider-bedded version of the HL-AL platform trailer, giving trade and construction users more deck area for the same 2.7 tonne gross weight. It is chosen when the standard HL-AL 3016 bed is too narrow for the load.

Buy or hire the HB511 if...
The wider step up from the HB506, for larger horses or owners who want more room in transit. The extra 12cm of internal width and 36cm of length cost 80kg unladen, which is worth checking against your tow vehicle before choosing it over the HB506.
