Pickup up the propane tank. Its big. Bigger than I planned. Its 11.9 gallons or 50lbs, and its half full and really heavy to wrestle under the truck, then to to bench press onto the jack...
But it fits, sideways, barely.
Tight on the spring hanger. A little trimming of the gaurd thing and it will slip up a little higher, should have ~1/2" clearance min.
Took some pics of the frame extension while I was down there. Its welded in, then a doubler is bolted across it.
