You can lift the wheel off the ground with the level up system. Many of us do it all the time.

I think I would say, within reason-- on flat, level ground, when out of the way of passing traffic, while still hooked to the tow vehicle, etcetera etc., then maybe do so. I'm sure the wording is in the manual for legal reasons.
We have the Rieco Titan system, it says the same thing. When changing a tire in our storage lot, I put an extra 6 ton bottle jack under the frame too, just in case.

Actually, I often find us on uneven (side to side) sites with the auto level lifting one side or the other completely off the ground, so flat level ground is not necessarily a requirement.

i agree this is a really simple and functional way to change a tire. But don't tell lippert. According to lippert, using the level-up to the extent of raising the wheels off the ground voids the warranty. Don't take pics. Lol.
When i got my 4100 in july, i could not level it with the level up automatically. The only way i could get it level was in the manual mode. The gal at lippert told me that it needed to be calibrated on a totally level parking lot, etc. She told me to go buy a 4' level and find a suitable parking area. Yeah right!!! Why didn't heartland do that? Them she told me that if i used blocks under the "legs" and the wheels came off the ground, then i was voiding the warranty. I have never used the automatic function, needless-to-say.
Just picked up my new 3875FB. I have full six way auto levelers, but I read in the manual not to lift the coach off the ground to change tires. How do I change the tires while out on the road?
Thank you in advance

I would imagine you would change it like someone who doesn't have a level-up system, with a bottle jack under the axle.

Very simple, easy and relatively safe. Best thing is it makes a PITA job a bit more tolerable.
1st time I had to change a tire was literally 1 hour out of having my LevelUp installed!
From the time I put the emergency brake on until the time I put it back in D for "Dat-a-way", was only 10-15 minutes.
If you are on a busy interstate with narrow shoulders you might be best off destroying the tire and getting out of there - or let the roadside service people take care of it for you.

Find a safe spot.
Trucks E brake on
If the location is not level, eg crown of the roadway, you may need some additional blocks under the jacks.
Trailer stays hooked up
Turn on the LevelUp, and access "manual mode"
Lower all 4 rear jacks until they just bottom out.
Alternate left and right sides to start raising the trailer.
The system will not allow raising out of side to side level more then about 2.5 degrees, that is one of the reasons for alternating.
If you can't get the lift because of the crown, then that is why you need the extra blocks.
On level ground you could expect to raise the tires off the ground Indy "style". That is four jacks all the way down and tires 4-6" off the ground.
I would suggest giving this a try long before you actually need to do it for real. Find and empty parking lot that is level.
As for all the naysayers about how dangerous it is, or catastrophic failures etc, it is no different then using any procedure to try and lift 6000-10000 on any trailer.
And IMHO, it is a much safer way.
Besides, even if the levelUp were to fail at the time you have the bad tire off, it will still have 3 tires (or 5 with a larger TH) to keep things up right.
Your cribbing support on the bottom of the jack sounds correct.....the issue is the POC (point of contact) at the frame. These RV frames are not 1/4" thick so the weight/load needs to be spread along the frame surface by more than a jack head.Since I don't have the level up system, I carry a 12 ton jack. I build up cribbing using the wood blocks I carry anyhow, and lift the frame. It's no big deal.
