Description

Heavy-Duty Adjustable Caravan Step for Safer Access on Uneven Ground with Non-Slip Surface and 300kg Weight Capacity

A stable and comfortable step makes all the difference when you're getting in and out of your caravan or RV.

The Supex 300kg Adjustable Portable Steel Caravan Step is built tough to handle the demands of regular travel, campsite use, and varying ground levels.

With a sturdy steel frame and four-stage adjustable height, it gives you the flexibility to set the perfect step height.

The step adjusts between 195mm and 230mm, making it ideal for sloping sites or setups where one side of the van is higher than the other.

Anti-slip rubber tread strips help keep your footing secure in wet or dusty conditions, while the wide 480mm × 370mm platform gives you plenty of space to stand comfortably.

Designed with strength in mind, it supports up to 300kg and has a solid build that stays steady under pressure.

Despite its heavy-duty frame, this step folds down neatly for storage in your van or vehicle. It’s a practical choice for caravanners who want a strong, adjustable step that’s easy to handle and built for Australian conditions.

Supex 300kg Adjustable Portable Steel Caravan Step Reviews

Frequently Asked Questions

Does the step lock into place once adjusted?

The step legs are designed to stay securely in place once opened. Each height setting is supported by a stable frame structure, and while there isn’t a separate locking pin, the anti-tip feet and rigid design keep the step stable under normal use. Always ensure the legs are fully extended before stepping on.

Can I leave the step outside overnight or in the rain?

Yes, the steel frame is built for outdoor use, but to extend its life, it’s recommended to store it under cover when not in use. Prolonged exposure to wet conditions may eventually affect the rubber feet or surface finish, especially in coastal or high-moisture environments.

Is this step suitable for use with motorhomes or trailers, not just caravans?

Absolutely. The adjustable height and strong 300kg capacity make it suitable for motorhomes, trailers, and even utility vehicles—anywhere a stable step is needed. It’s a popular choice for all types of travellers.
