Has anyone used any of the generic boat foam you can buy off Amazon to adhere to the lower truck panels for a little bit of insulation/sound dampening?
Man I’ve been thinking about doing this a lot. It’d have to help some
Going to give it a try next week. Wonder if there really any benefit for going for a slightly thicker foam?
Probably negligible R value, I’d be concerned going too thick would interfere with closing properly, as my latches get angry if my mtb jersey gets caught when closing
There some 3mm foam adhesive on Amazon. I was thinking this wouldn’t interfere with closing the panel. I guess worse case scenario, I could take my time and cut the foam where the braces are so it won’t obstruct. My only concern is condensation.. Perhaps, a marine grade type Fabric like the headliner would be a better call ?
How tight is your bed sealed?
I’ve slept in my bed “stealth” a couple times and never had any issues with condensation.
Though, due to the gooseneck mechanism of the Rivian tailgate, my bed is not airtight.
Maybe if I was cooking in the bed during inclement weather that may be what tips it over the edge…
