Practical ownership tips
Towing suitability
At 1,700kg MTPLM, your tow car needs a kerbweight of at least 2,000kg to meet the 85% guideline. Check towing capacity by reg or use the towing calculator to compare a specific car and caravan.
Available payload
The Lunar Lexon 640 has approximately 185kg of user payload. This must cover all personal belongings, water, gas, awning, and accessories. Overloading affects handling and is illegal.
Before you buy
Request a habitation check or damp survey for any used caravan. Check the service history, tyre age, chassis condition, and whether the CRIS registration matches the seller. Specifications vary by year and trim level.
