By now my 2015 Lunar Ariva (less than 2 years old) will be back at the Lunar factory having the entire front panel replaced for the second time. Yes, that's correct. 3 panels in less than 2 years due to cracks appearing in the fiberglass. Very off putting. I suspect that Lunar have gone too far with weight reduction. The chassis on my present Ariva. does not appear to be as deep or robust as on my previous two Arivas. Lunar have managed to reduce the Unladen weight by 40 kgs in spite of fitting a microwave in this model. Could that be causing flexing whilst being towed ?? Hope I get the 'van back for my summer Hols. hmy:
