Hey OP - Thought you'd already done this. You're gonna love it!!!

And if you haven't already done it replace that way undersized front Anti Sway Bar too !

J-D, I did the front sway bar last year. I am doing the rear one this week. It just arrived.

Affirming what many already assert. That I truly don't know which end is which...
If you have a hard surface to work on, or maybe more so if grass or gravel, put cardboard down. I hang onto a major appliance box if I can. Slither on that, then take the box the bar came in. Close it with the bar on top and slide it all under. The few inches made positioning the bar a whole lot easier.
Really seems to me your bar mounts differently than ours. Not better or worse, just differently. Yeah, just looked again. Same part number, bar and axle brackets look same but the end links that mount forward of the axle have less of a "home shop made" look to them than ours from several years ago do.
If there's risk anywhere... NOT from the coach falling on you since no need to jack it up. Just find the right holes to get the best angle for those end links. Then be sure you don't pinch/crush any wiring or lines on either side of those frame rails.
EDIT: Or yourself... Removing a hitch once, nut up in the box frame wouldn't back off. So I grasped the hitch, put the 1/2" air impact back up and blip the trigger. This instantly told me that I had also bumped the tool from OFF to ON. Predictably I dropped the wrench. That might've been OK but it was an old wrench and the 3/4" socket fell off, rolling out of my reach since I was attached to the vehicle by the left thumb. Took me awhile to get out of that one. Work with a Spotter!
