The Knaus SUN I sits at the upper end of the A-class market, competing with models like the Adria Supersonic 890 LC and Swift Kon-Tiki 894. While the Adria offers a higher 5500kg MTPLM and the Swift provides a more accessible entry price, the Knaus distinguishes itself with its specific 1050kg payload and 8.82m German-engineered frame. The choice between these vehicles often depends on whether the buyer prioritises the Knaus yacht-style interior and double-floor insulation over the different berth configurations or weight limits found in its rivals.
Worth knowing: Specifications and prices can vary by model year, trim and optional equipment.
Ownership and maintenance tips for the SUN I
- Utilise the underfloor storage for heavier items to maintain the low centre of gravity provided by the AL-KO chassis.
- Regularly check the seals on the panoramic windscreen to ensure long-term visibility.
- Test the electric drop-down front bed mechanism periodically to ensure smooth operation.
Common mistakes to avoid
- Underestimating the 8.82m length when navigating tight UK campsites.
- Neglecting to drain the double floor systems during periods of extreme cold if not in use.
Worth knowing: The 5000kg MTPLM is a fixed limit; always weigh the vehicle when fully loaded to ensure the 1050kg payload is not exceeded.
