I have a 2003 Holiday Rambler Endeavor RV which I have owned for the past two years and have done several repairs myself with the help and advice of this forum.
I now have a problem with the soundproofing material that lines the area under the floor and the access hatch area around the diesel engine.
The adhesive has failed and the soundproofing material has dropped down on the top of the engine. I have tried using a spray on contact adhesive but the weight of the soundproofing material keeps letting the material pull loose and fall down again.
I could use some good advice what to use to bond the soundproofing to the metal again and the best technique to apply it and fasten it.

I would buy a new sheet and replace with a lot of the sound proofing it’s not the material but the anti vibration from the product being stuck to the housing that reduces noise also newer products perform better.

I had the same problem and used the some flooring threshold type strips that had predrilled holes in it. I used these around the perimeter and spaced out in other areas. Used short screws to pull the insulation back into place. This has held for ~8 years.

Spray glue doesn't really work on coarse material. Some construction adhesive or brush on contact cement may work They make fasteners for foam boards if wood is under or plastic cap nails . We use glue on insulation anchors at work then a special push on washer locks to the anchor pin but I don't see both less than 40 for bags. There is a plastic version as well.
