A super photo Tom and I know that we can count on more top tips from you.
The last few days whilst away wild camping and wiping the windscreen down both mornings, I was thinking to myself “if only I could improve this” and a cursory check of the condition of my fabric covering and tapping convinced me that it was a lot of work probably not required…..now with what you have discovered in yours, I am disturbed again!
Good idea to take an observation break.
I am hoping that in the meanwhile you will be coming up with another of your groundbreaking ideas – other than just marine ply and find a solution that will vastly improve air/sound insulation.
Best wishes for the project, Tom.
