Current pre-order MDC website catalogue snapshot accessed 2026-08-21. Tare, towball weight and payload are explicitly published by MDC as approximate; ATM is the published rating. MDC identifies this as a tandem-axle off-road caravan. Travel dimensions and annex size are explicitly marked TBC, so length, width and height remain null. Year 2026 denotes the verification snapshot, not a manufacturer-claimed model year. GTM and axle rating are not published and remain null.

Match the model year and configuration to your caravan compliance plate. Confirm fitted options and measured travel weights before relying on catalogue figures.

Matching & Towing Considerations

ClearPath Educational Observations
  • This caravan has an ATM of 3500 kg. This is its rated maximum, not its measured travel weight. Check the actual loaded caravan mass against the vehicle and towbar towing limits, and check GVM, GCM, axle and coupling limits separately.
  • Ball weight (towball download) of 250 kg must not exceed your vehicle's towball download limit. This weight also reduces the tow vehicle's available payload.
  • Ensure the combined weight of the vehicle and caravan does not exceed the vehicle's GCM (Gross Combination Mass).
  • Water, gas, cargo and accessories all add to the caravan's loaded weight — the ATM is the maximum, not the typical towing weight.

Things to Verify

ClearPath Educational Observations
  • Compliance plate figures (ATM, GTM and tare) — these are the legally binding numbers for this specific caravan.
  • Actual loaded weight on a certified weighbridge, especially if accessories or modifications have been added.
  • Towball download measurement with the caravan in loaded, ready-to-tow condition.
  • Build year vs model year — specifications can change mid-production.
  • That the variant and configuration match your specific caravan (floor plan, axle count, options).
