We have a lunar quasar 462 which at the time we purchased was the right layout for us with good build quality and not heavyWe have a Lunar 585Si and have had no problems from new (2008).
The weight is a bonus and we would upgrade to another Lunar when the time comes.

Delta 640 2006 similar probs I thought different company owners would improve matters,it didn"t.Hi D
2003 was a bad year for Lunar as far as I am concerned,I bought a new Lexon 640 EW T/A and the list of faults was endless,it was so bad I sold it 4 months later,the first thing you should check would be the hieki rooflight and the freedom of the slide,the roof of my lexon was so buckled and twisted that it fouled when trying to open it,this was not an isolated incident as several Lunar owners at that time were site wardens for the CC&C and we used to compare notes.Mine was so bad,it suffered from floor delamination,
furniture parting from the walls
draws falling to bits
door hinges coming away from frames
ingress of water from just about every seal
suspension fouling wheelarches
and the fixed bed base was steel mesh and a foam mattress which was really uncomfortable.
Freelander by the way was the brand name for mendip caravans.
I do hope you find a good one at the right price good luck.
