Slow drains
Proud owner of 2023 3793RD. Issue with black and gray tank drains. Previous 5th wheel, drains gushed when first opened. This one, both drains just trickle.out slowly. Almost seems.like valves are not opening completely. Trailer is only a month old and been this way since new. Galley tank drains normally. Anyone else seen this and what was the solution? We live in it full time so return to dealer is not an option.
