Couple things:
JRscooby: the foot print of the jacks are 12 inches x 12.xx inches and stack inside each other if the center lift is removed. I have a couple plastic steamer trunks I keep in the bed of the pick-up, one for sewer hoses and connections and such, the other for carrying an extra jug of DEF and hoses for my air compressor. I removed the jug of DEF and the jack stands fit nicely, with adequate room to still wedge the jug of DEF in there also.
About weight, the center lift is removable. The base by itself is not any heavier than that jug of DEF I manhandle. The center lifts are probably a good 10 pounds all by themselves. So, if moving them around, each piece by itself is not that bad. I'm glad they can be broken down though.
The only draw back I see, as mentioned above, is the possibility the feet would sink, especially if on dirt. I'll be experimenting at home, but am now considering a square plate, maybe 13 or 14 inches square to fit under them so the feet won't sink in soft ground. (still working on this one).
Lantley: About the difference is extension length on those legs. I don't know why. After I unhitched, I hit the Auto Level and everything started working as expected. The front jacks started raising and everything appeared to be OK. When the Lippert system signaled, "grounding rear jacks" it started lowering the back ones and quickly went into an error, indicating the front was low. No matter how I tried, I couldn't get the front jacks to raise higher, no matter what, I kept getting the same error. So, figured I'd reached my total length, which was only 13 inches. So, maybe the auto level system cut something out. When we left the campground, all the jacks retracted OK, and the error went away.
At home, I did not hit the auto level. I went straight to raising the front landing gear as high as it would go. After I was done playing with everything, I manually adjusted the front landing gear to approximate level, and then hit the auto level, and it leveled out and anchored down just fine, all 6 jacks.
My dealership repair shop guy did tell me the trailer had to level close for left-to-right. It looks like, it has to be somewhat close to level front-to-back (or within 13 inches) for the auto level to work correct. That's the best I can figure.
However, with the new jack stands, I can now get the front up high enough (if and when this situation occurs again). I've just go to figure out how to prepare for this if the trailer is ever parked on grass on a slope. The way we travel, we just never know where we'll end up. After all, it's better to be prepared and never need it, than not prepared and need it and can't get to it.
Thanks again. I'm still very much appreciative for this idea. I was dumbfounded and never in a zillion years would I have thought of using stationary jacks.
