I have a 2018 m27 and have a similar problem with leveling. When closed I get refectory level. When the close is extended it is tilted to the slide side. Drives me nuts ! The frig door and bathroom doors fly out when opened. I have seen that some users add an additional 1” block under the slide out side tires to compensate and once the slide out is opened all is well. Has anyone tried that?
I am am camping in two weeks and will give it a try and let everyone know.

Hi Ron,
It's been since 2004 since I had a travel trailer but my recollection is:
- Level the trailer side to side using boards/blocking under the low-side tires
- Disconnect from the tow vehicle
- Level the trailer front to back using the tongue jack
- Put all stabilizers down to stabilize the trailer
- Run slide room(s) out*
* This said, I didn't have a slide in my 204 unit, but my understanding us that slide rooms go out after all leveling and stabilizing is done. And then there is little to no change in the side to side level.
Perhaps this is in fact, what you are doing, yet you're still experiencing level change after the slide is out. If that's the case, you may need a qualified servicer look at it.
