If I recall I think they make stabilizing jacks that bolt or clamp on to the trailer frame.Yes, there are four scissor jacks.
They are a bit safer and more stable than a scissor jack that can slip. Might want to look into that.
I remember when you first posted y'all were getting this. Glad it has met all your expectations.
Remember we will need a range report not only on your first hunt but also on the trailer.
I am happy for y'all.
