Thank you for your interesting and lengthy explanation of the issue and means of resolving it.
Please forgive my confusion, but my background is healthcare, specifically hospital pharmacy; I am not an engineer.
I am estimating the total weight of my 40ft coach to be in the range of 5-6 tons, with contents.
The screw-type jack stands do not appear to support any significant weight; would 1-ton screw-type jack stands distributed every ten feet on each side of the coach be sufficient to handle the coach weight, or do I buy larger capacity ratcheting stands? And what capacity stands?
What about the hydraulic jack--are we talking bottle jack and in what capacity?
Your perspective and rationale are both reasonable and cost-effective.
I thank you for your time and efforts.

Personally I would look at getting two sets (each set has 4 stands) of the Camco 44560 Olympian Aluminum Stack Jack Stand which go for around $34 at Amazon and each stand supports up to 6,000lbs more than enough.

Just for convenience I would get like a 6T bottle jack that would run you less than $20 again from Amazon.

So for less than $80 you would have all you would need.

Now if you wanted to go the Roll Royce route get the Camco 57371 Olympian Telescopic Jack ($36 each), but those aren't all aluminum and would require more maintenance than the Camco 44560 stands and I'm not sure how much more they are buying you.

As an experiement you might just invest in the bottle jack and see if by using it along with what you have now you can get enough support to satisify your needs.
