Chad, I agree with Tom about heat.
Way back when Interstate was considering the manufacture of Gel Cell batteries I was given the opportunity to install them and test them on our first coach. They were for the house and at the time Liberty stacked the house batteries in the engine compartment over the chassis batteries.
After some failed batteries we started measuring temps in that area which would be just about a foot away from the bulkhead your Victron devices are mounted on. The temps were as high as 185 degrees.
I would contact Victron and see what their engineers suggest. You cannot lower the temps in that area because the air flow is mostly from the radiator fan pulling heated air and blowing it across the engine which has the heat of the engine, including exhaust manifolds and turbo intake tubes which can get to and exceed 1000 degrees.
It will involve a lot of cable, but can you relocate them to under the bed with a small fan pulling room temperature air from the bedroom floor?
