So here are the pics of the fence post sewer pipes. I ran two sizes. Two small 4x4s for the sewer pipes and one 5x5 for the ladder. The reason I placed them here is because in the FR3 the traditional location to place these fence posts ( the bumper or the undercarriage) were not suitable. I considered placing the fence post under the back faring under the frame extension there are two u shaped skid guards. They would have fit up in there and found it would have required I add a 4x4 panel door. So instead I chose the LP panel location instead. .
In the panel I added a piece of angle iron cross wise on the existing frame for the LPTank on the outside end and hangers on the frame substrate behind the steps on the curb side.
Took advantage of the panel space. Note: my 30DS 2014 has the original swing down panel doors.
