Flippac lid crackling when I lie on it

[Sheils]

Hi all, I bought a used FRP flippac (I think from 2012) and have been using it daily for about 5 months. Recently I've been hearing a crackling noise in the roof/bed platform when I'm sitting or moving on it a certain way. Today I heard a more substantial cracking sound. I've read about the torsion bar problems, but has anyone on here had a problem with the fiberglass cracking/giving out?

I'm 140 lbs and my dog is 70 lbs, which I would think is in the normal weight range, but we are using it every day so maybe these things give out...

Mine is a '12 and does this also - I think it is common when there is a point of pressure rather than more dispersed pressure. I wouldn't sit on the opened bed without a mattress to distribute the weight but I have never noticed any structural damage like cracks in the fiberglass.

Mine has done it too since I got it (used) I think it is the lack of glue between the two fiberglass layers and whatever material. I have not seen any damage from the noise.

Ours does as well from time to time. We've determined that it's the plywood that is embedded inside the lid.

Yep, mine has been doing it for 5 years, no problems. Its the top layer of fiberglass cracking its poor bond with the plywood insert.

I think it is the lack of glue between the two fiberglass layers and whatever material.

The material is a honeycomb type of cardboard that is impregnated or sprayed with some kind of epoxy. So, I think the cracking sound is the normal cracking that that honeycomb stuff makes. Although I do wonder if each cracking sound suggests a little wear-and-tear on the lid. My FP is 15 years old and still cracks. It sounds a little unnerving, but my camper still functions as it did when I bought it 7 years ago.

Thank you everyone for your replies! This is exactly the sort of reassurance I was hoping for
