here is a fix for the screw on nuts that hold you pushout closed.
This is how I fixed my push out nuts, that keep your push out closed when it closed up.
I went to Lowe's and bought clear coated cable 2FT and used the round yellow crimp connector's.
I cut the cable in 1/2 to 2 1 FT sections, then crimped a connector on either end.
after I stripped about a .25 of an inch of clear coating of the cable, I riveted one end into hole where the original rubber/plastic strap pushed into on the nut.
the other end I screwed it with screw on the push out where the original strap attached. working great so far, when I bought the camper 3 weeks ago the guy giving me the run down on the camper said one of the straps broke while he was turning it to take it off.
checkout the pic of what I did if you need to fix your's.
