Tripping on caravan steps is the single greatest cause of injury to caravanners.
Your step needs to be stable, strong and durable. Ideally it should also be capable of being stowed safely in the van without causing any damage if it bumps against woodwork and, most importantly, should give you easy and safe entry and exit.
All Milenco models have a base much larger than the step so standing on the edge presents virtually no chance of the step tipping over.
