I was very interested in trying the jacks near the axle, but was reluctant to spend the money without seeing what the results would be first. I realized a few weeks ago that between our truck and the wife's car, I had enough jacks to test this without spending a dime. Tried it on our last trip, and proper jacks are now on my shopping list. I will likely bolt a pair of manual scissor jacks up as I am too cheap to splurge for electric.
