If you have a serious accident and a roll over in a slideout model of any motorhome, the chance for serious injury significantly increase. Wind Noise - Seal designs have improved but in most designs there is a noticeable wind noise right behind the driver. It is worse if you ride on the couch inside the slideout. Because of imperfect seals some slideouts cause a significant wind noise while the coach is in motion. Older slideout designs require the manual installation of some clamping devices to hold the slideout in while the coach is moving.
Recent improvements employ a locking device that clamps in the top of the retracted slideout.
This is just one more device that can fail. Water and Dust Slideouts have gasket material that is used to keep the water and dust out. Because of the significant lineal distances that need to be sealed, this gasket material is very critical and must be installed correctly. Any misalignment of the slideout can cause serious damage to this gasket material. In the worst cases the slideout must be removed from the rig to put new seals in.
