I have a large Kampa Air Awning, It is a 4metre version and is therefore , I believe too heavy for the Fiamma already fitted. The new MH is slightly taller than the last and the Air Awning sits too high. The Kampa Video shows it being fitted with the roll out awning half out. They then wind it in but it is a very short model. Now looking to possibly fit an extra Awning rail to the side of the MH below the Fiamma. I would like a whit anodised one but can only find Aliminium rails in sections . Not wishing to use screws, do we think that Using Sikalex to secure the rail would suffice ? It would of course needs a set of steps to slide the awning into the rail. Any thoughts?
