I have seen many photos of CLP/SSM in various trunks posted here, mostly there was water damage due to a leak somewhere.
I took my trunk apart on a project and saw my CLP/SSM for the first time, what struck me was the fact that it was on its side and sitting on a wedge-shaped block of foam that raised it above the bottom of the trunk. If most CLP/SSMs are positioned like this I do not know but the block that raised the side of the CLP/SSM almost flush to the floor level of the trunk was not shown in the photos I have seen and certainly raised it higher if there was water in the trunk.
See the setup in the photo below.
