I had just assumed they all happened at the same time, but I was a little surprised to see 5-lug wheels on a leading arm axle.
... And I see now you were busy editing while I was asking questions. You have addressed all except the 4-lug to 5-lug change, which I'm guessing now is mid-late 80's. Thanks for satisfying our curiosity.
One more question... Do you have any idea of the history of the weight
ratings on Scamp axles?
I honestly don't think that the Scamp factory owners could give you the exact information you are asking for. They have always been busier making trailers than keeping records.
( plus the fire?)
Sometime after converting to 2200 and 3500 pound axles, after '86 and likely around'92+...ish. I don't recall a Scamp hubcap wheel with 5 lugs.
Early Scamps had 2200# axles on the 16s and 1200# leading arm axles on all 13s.
Circa 1981? the 5er appeared and I am sure it wasn't long (maybe the first year) that they got a 3500# axle( PURE CONJECTURE)
Not sure on the 16 though much earlier than the 13 Maybe all the way back with trailing arms??? I have seen leading arms on 13s as late as 2003.
I am sure there were some trailing arms as far back as 96.
My guess is that13s were all trailing arms after 2003 (there may be exceptions).
All after fire frames on the 13s (or at least when they ran out of prefire frames) have been 2" ball couplers. This was the same time that they dropped the kickstand type tongue jack and went to the vertical ones.
My thought is that the upgraded frame came about the same time as the upgrade to the 2200# axle on the 13. Circa 1996 , but definitely post elephant hide earliest could be late 1980s. I have only mic'ed an early (circa1980) and my 2004 but frame cracks seem to have become a lot more rare post elephant hide.
Most of this is out on the edge of my knowledge and I invite those more positive to chime in.
