With the required mounting kits, the 85 gallon SubMount Freshwater tank can fit securely under your Boxxer 318, 318HP, 423, XL, TITAN 325, TITAN 425 and TITAN 575. This system maximizes van space by mounting the freshwater tank beneath the truckmount unit. Note: Installation with a TITAN 575 in a Chevy or GMC van will require modification and additional expenses. We recommend TITAN 575 installation only in a medium/high roof Ford Transit, Dodge ProMaster, Mercedes Sprinter, or Box truck.
