Swift Escape 664 Towbar on a 2011 plate?

[PaulC70]

Hi all, so joined up as looking at buying a 2011 swift escape 664 which already has a towbar on it, but I have seen conflicting reports about whether or not it should have one fitted due to being a light chassis? Now I don't even know what a light or heavy chassis is so just really looking for clarification as if it shouldn't have one I don't want to buy something dangerous?

Any help for a newbie greatly appreciated.

PROBABLE REASON THEYVE SAID NO TO TOWBAR ON LIGHT CHASISIS IS IT EATS INTO THE PAYLOAD
OOPS CAPS OF NOW

We had a 664 and was advised not to fit a towbar due to the lightweight frame work. Take a look underneath and you will see what I mean .
