Thank you for those picture! That helped me a ton. They pushed it back into the hole and it's sitting very snug now with no movement. It may have broke one of the small twist lock tabs. But it's not moving.
This truck is my old one and gets used on the pipeline right of way now. It snagged on some brush apparently.
Lol.... well. The truck was designed to use and that is being done!! These guys take good care of them. Very conscience of maintenance but they have to get them 30-40 miles down a right of way... sometimes that's not very easy.
