We are building a garage for our MH and have found the need to install a trench drain in front of the garage to handle some water run-off from the driveway sloping toward the garage. This is to avoid excessive slope we would need if we didn't do the trench drain. The slope could cause clearance problems either at the front and/or the rear of the coach.
Question. What load rating or type of trench drain do we need? Our back axle weighs about 19,000 lbs. and the front axle weighs about 12,600 lbs. Does anyone have any experience with this? Thanks for your response.
