We recently upgraded from a Vista 27N which had easy under-the-steps battery access to a 2018 Forza 34T whose battery bank is in a rear passenger side compartment that is difficult to access for water fill maintenance. I confirmed with Flow-Rite that they do NOT make a quick fill system for the 4 X NAPA P/N 8231 deep cycle marine batteries installed. Has anyone solved this dilemma? Custom slide out tray?
