At least with two Bigfoot-style jacks on the front, there might be a better chance of reducing the damage.
You are welcome, Ardra. The argument that 3 points make a plane, and a tripod is used by surveyors and such because it is easy to level does not stand up (no pun intended ) with me. A tripod is easier to set up, but is not as stable once set up as a quad-pod. If I had a small model of an RV on 3 jacks setting on the floor -- I could easily "twist" the front end on that single pivotal point, but not the rear. All three legs of a tripod come together under the load and equally share the total load, whereas the 3rd RV jack is 4 or more times farther from the other two than those 2 are together. So the rear two give no lateral support whatsoever to the front end load and do not share that load.
Did you know that Bigfoot named their company Quadra Manufacturing to emphasize the importance of 4 jacks vs. 3? ???
