Does anybody know about the construction/framework of these caravans?
I recently bought this classic caravan and have noticed one small area of old rot which is completely dry and was not wet with the recent rain. The area of rot is about 5 cm x 5cm.
The van was resealed a few years ago and has nice new stainless steal screws over the awning rail.
The only thing that is concerning me is that all the walls seem pretty flimsy. When I push on all the interior panels the aluminium panels move on the outside in the area that i'm pressing. Is this normal on these old lightweight vans?
I have been pressing on my dads newer van (approx 1995) and this seems pretty solid.
Have construction methods changed?
I have recently seen a few old Thomson Mini Glen caravans and noted that all these vans had the same issue.
Not sure if I'm paranoid but should I assume that the framework behind the hardwood panels has rotted away? However, the hardwood Panels are solid to touch. not wet and no staining.
older vans have thinner walls, and/or less insulation, mu 77 monza had no insulation in the walls in most places, and in others only thin polustyrene, the sandwich construction of newer vans leads alot to extra rigidity.
I would consider borrowing/hiring an endoscope to get behind the panels to have a look if you are concerned about the framework.
Hi, the chances are it's a frame and clad construction, basically, a wooden frame clad internally with board, outside aluminium, (early vans were clad externally with oiled hardboard and had canvas roofs) repairs to these early vans is fairly simple just a matter of removing the moldings and external covering as carefully as possible , which then exposes the framework, replace any damaged/rotten framework, replace outer cladding and moldings with sealant where appropriate, clean up job done.
