ok so I obviously didn't research enough before that last post on the c jacks.

If you get the correct size, they would not be overkill.
But as far as the homemade jacks under discussion; if mounted correctly, ie 45 degree angles, etc, then they should still provide adequate support just the same as the c jacks. with possibly a bit more setup work. (Also assuming strong enough materials are used) I think that they could be beefy enough for a tear
StandUpGuy,
with the threaded support, do you think you could fabricate it simply and not have the threaded rod straight down in the closed position? seems that might catch on things and be a hazard while driving, and maybe be a pain to turn to set up too.
