I looked into a Hayman Reese towbar a while ago, and it was listed as "needing minor alterations to chassis" to fit them. They actually attatch to the rear tiedown loops and bolt up to the chassis. IIRC this is where the "minor modifications" come in, as they would need to fit some crush tubes to the chassis to allow bolts to go through (owing to the full box section chassis). Compared with most other vehicles we are a bit unusual in being fully boxed all the way to the end of the chassis, most end with a length of "C" section, making attatchment of a bar easier.
