Slide not staying closed

My thought would be if it's electric then the brake isn't holding. If it's hydraulic then the system has a bad seal and is allowing hydraulic pressure to bleed off.

A temporary solution perhaps but any trailer with a slide that didn't originally come supplied with slide locks shouldn't ever require them. My 2014 Coachmen Freedom Express has a slide but certainly never came with any slide locks nor were they recommended for use with this trailer that I know of. I doubt the OP's Coachmen is any different and as such I'd want to fix the problem, not just sidestep it with one of these aftermarket slide locks. JMO.

Thanks all!

On a previous trailer we had I just made my own using standard wood doweling...

Hello Dick, thanks for the idea :-) Just so I understand, you use some type of spring rods inside to secure the slide closed?

Other than a cursory look on your part to make sure there isn't anything obvious causing this (which you've presumably already done) I'd be booking an appointment to have a qualified RV tech ascertain just what the problem may be and the appropriate fix. Yeah, it's a cost but that's potentially always the cost of owning any trailer with a slide. You want the additional space you take the risk. ;)

My Power Gear motors have brakes that prevent this. Brake is on when the motor is off.

When the slide is closed the rods go between the solid wall on the inside and the back of the short wall(s) of the slide. We put one on the left, one on the right and one in the top middle.
Our rods are about 40 inches long but that will depend on how deep is the slide. They have rubber feet on each end to prevent marking the walls.
