I took my time, and by myself I spent about 3 hours. The biggest issue was with the Ranger plastic bed rail covers. There is a gap between the side of the plastic rail cover and the steel bed. The Lomax cover comes with spacers to fill in the gap where you put the track clamps. The issue was that the gap varied from 1/4 inch to almost nothing and is not the same on both sides. The time was spent selecting the right spacers and clamp settings to make sure the track was level. Not sure how other clamp on covers handle this. Will have to wait for some rain to see it leaks. This cover does not need drain tubes.Looks awesome! How was the installation of the bed cover?
