Welp here is how I did it. I have an advantage in that I have a big truck with air bags. I could use the truck to lift the trailer in increments by inflating the air bags then chocking the trailer pin, deflate and add more lumber to the equation. In my case the jacks would not lift the rig but would hold it long enough to set the wood to make another lift. We left the truck in place as a safety stop should the situation go south on us. The tires were blocked and brakes set.
This is a blog a buddy of mine has and there are 3 pix of the "system" the Lippert tech (they sent him to Northern Washington state from Portland OR.) and I used to get the job done. Jacking the rig up is the only really hard part.

As far as measurement is concerned you might be able to get the lengths (stored and extended) from the DRV factory on your unit. That will tell Lippert what size ram to send.
FWIW we only replaced the bad ram and all others are still functioning fine to date. Knock on wood and cross fingers.

We are close to Reno now and will be in Ventura County, CA for the winter, so that may be interesting. So Motor 31, how does that work to hold the unit up while replacing the ram???
