So I decided on the BAL Hide-a-spare, specifically the MODEL 28218: 70” to 75” frame, I-Beam Underslung mount for trailers with enclosed underbelly. There is plenty of room from the tire to the lp gas line, with room to spare. Probably could have gotten away with the non enclosed belly one. But I am happy with it.
As you can see in the pictures, it is no lower than my grey/black tank drain pipe and it was a fairly simple install, just had to get bolts/lock nuts/self tapping screws from lowes.
