All those dually guys.... for some reason all their tools are efing a lot of the time.
I'm a single rear wheel guy and all my tools have never done that.
I'm sure glad they quit making 'Dullies' though. I don't know what I'd do with those extra spare wheels on each side.
I think there are two problems with the NL drawer guides. One is I found them to be too low in the back of the guide and not square with the face frame of the drawer cabinet. I had to shim each one up with a shim and hot glue. Second, some were not attached proper and were falling down too low going out of level (well on a camper level means nothing) it has to be square with the cabinet front. Others I had to make a better support as the rear part of the guides were plastic and breaking falling. This was on a brand new NL camper.
BTW, my NL likes my single truck they have been married now for 11 years because of that.
