Summarizing my earlier posts ... warm is > 60°, cold is < 40°. When warm, everything is fine. The bus sits and doesn't move. When cold, the left rear drops. With the tag up, it still drops. Do all bags have to leak for it to drop?

Six months ago, Prevost replaced two 5-way valves and 4 quick-fill tank drain valves in that area. A year before that, they replaced a Burkett valve with a 3-way 2-position Norgren.

Much thanks.
