I installed a dual house filter system in my RV/motorhome. As there can be a bit of weight from both canisters filled with water the canisters can flex and potentially crack the mounting board. I designed a support beam that can be screwed into the backing board or velcro'd (3M Loop is my preferred) to secure in place as you see fit. This should prevent the canisters from flexing and putting stress on the mount or attached panel.
