So friend #4 (Pete) messaged me today with more information…
I was concerned about the drop axle in the lead photo. When I originally saw the picture, I thought that the drop axle indicated that it was trailer/pup set up like you see at gas stations. Pete reminded me that a truck and trailer set up like that would be really hard for some tight farms. He suggested a 20’ tank, to which I asked would a 25’ tank be big enough to require the use of a drop axle. Pete with all of his knowledge driving trucks said yes a 25’ tank would be appropriate for a drop axle set up like the lead photo. He pointed out as only a trucker would know that a heavy truck without a drop axle would overload the steering axle, hence the need to prove the drop axle.
The auger was styrene tube I had on hand, not sure the size as I just grabbed one that looked close. As for that motor, its actually half of a transfer case box that I had in the kitbashing box. I have since destroyed it in the process of being removed, but the good news is I had previously made a casting of it for my Pettibone Speed Swing.
