Hi Royston
Ive read postings on this forum for quite a while and the conclusion was I bought a new Coachman. I Dont recal any newish Coachman having this problem and I bet they also get their panels from the same supplier. They use acrilic capped ABS and i wonder if the faults on other makes like Bailey Swift and Avon etc maybe down to construction methods. We all know Coachman are very heavy in comparison to most other makes but does that mean they support the front and rear panels better therefore less likely to twist and cause cracks etc.
Coachman also I belive test each year on the pave at the Alko test track in Germany and therefore maybe more knowledgable to where their carvans are prone to stress, twist and vibration and beef up accordingly. They are I'am told the only UK manufacturer to do this.
I also noted no issues with Hymer and other German makes who are also rather heavy.
Does anyone no of any cracking on Coachman and German caravans, they seem to be better built I think.
Regards
Alan
