John, been held up by weather for a few weeks, not much done. I'll have to make a rock guard, I guess. The axle issue is still in flux; the torsion "set" on the spindle/hub is about 30 degrees UP and FORWARD with the trailer sitting level. Plenty of room above the tire for "bounce". Don't know how much it flexes when load is applied; any ideas on how to test it? Doesn't seem to sag but I've only pulled it 1.5 miles from where I found it to my home, couldn't see much on the narrow road with no mirror extensions! I "think" it's OK but need to KNOW before I buy new tires/wheels/axle! Has a 4 on 4" hole pattern, 13" tires
. (And the ones on it are original! From 1981, and they hold air! Not going far with them!) Want to go with 14" tires
but the wheels are hard to find with the 4 hole pattern; may have to change out the hubs. Too many questions until I can verify the torsion soundness! Keeping it "original" isn't my goal, really. Just want it to be "right" and tow well, last long time! Thanks for the rock guard info; wish the Burro's had one.....
