[Rhodes22-list] Axle locattion

[Graham Stewart]

Sorry for the confusion. Because all of the other dimensions matched the
drawing I used the distance from the axle to the back because it was the
easiest measurement forgetting that others might have a different structure.

The distance between the center of the axle and the point where the
extension enters the trailer is 165" while that distance on the drawing is
172"

I agree with Todd that the reference point should be the center of the ball
socket.  That's where the tongue weight is measure and where the towing
force is applied. - Rob

By looking at these old drawings, I guess the datum point/benchmark really
should have been the center of the ball socket, which would have better
standardized the tongue weight (and balance). That would have to assume the
coupler and extension lengths were somewhat uniform.

Measuring the axle position from the rear of the trailer frame or the rear
bunk support is not the best reference.
Also, the angles of the bunks are a little off (I was never good at trig).
Thankfully my carpenter's calculator has a rise over run function. The
angles for the bunks are closer to 22.5° in the rear and 37° in the front
(from horizontal).

I seemed to remember there was approximately a 6" difference in axle
positions between owners' trailers, but most reported the more rearward
dimension so I changed the drawing. There may be early drawings of the
trailer in the archives before I edited the drawing which show the forward
measurements..but I do not know.
