Leveling a Bounder with wood
I am wondering how bad it is to level out my RV lifting just one of the two dually tires on one side. Is this going to damage my axle or is it completely okay?
I read that these tires are rated for weight exceeding the forces that are applied to a single tire please let me know what you think

Honestly, I don't know, but personally I would use a wider piece of wood under both wheels and be done with it.
It just feels better/safer and wood is pretty cheap compared to any possible damage to a tire

It has dual tires for a reason - one is not enough to carry the weight. Additionally in the picture you don't even have the one tire completely supported. Build a wider and better support that fully supports both tires. There are several threads here findable via search feature regarding building blocks and ramps.

I agree 200% with the above poster. Never put all of the weight on one rear dual. It is bad enough when driving and drop off into a hole where only one tire supports the entire weight for a brief moment. Also like stated above you don't even have one tire fully supported. I think you are asking for trouble doing this. Check your owners manual and see what it has to say. All of my manuals with a rig having duallies stated to support both tires when leveling.
Can you imagine what is going to happen it the outside tire goes flat suddenly, the weight shift is most likely going to cause the MH to fall off the blocks.
But it is your rig and so you can do what you want with it.

Depends on how long you plan on keeping it supported on 1 tire. When we use 6 post lifts to lift up a 45,000lb Essex, the drive axle lift ONLY lifts from the outside tire. I mean, there's only 1 air bag per axle end (usually) and that's enough to support the weight of that corner. I've had air bags apart, they aren't that thick.
In other words, in my opinion you're fine.

Wood under on tire places all the weight and stress on the one tire.
When I had my Mirada, If I needed to use wood under the rear to get it level, I put it so both tires were on the wood.

Damage to the axle is not the issue. Damage to the tire IS. Every tire manufacturer, and every RV manufacturer, says that what is shown in your picture is wrong on two different levels. 1st, BOTH tires should be supported. 2nd, the entire tread width should be supported. You are actually supporting the entire rear corner weight of your RV on LESS than one tire.

Couldn't one just weigh one corner, or both and take half for a rough estimate then see what the max loading for the tire is?

Leveling a Bounder with wood.
You guys better contact the lift manufactures and give them your insight. I work underneath motor homes all the time with the weight only on the outside tire. Never been concerned about it

When something "just looks wrong" and / or you have to ask "is this wrong?" it usually is......... And that picture, just looks WAY wrong for more than one reason.
It may or may not lead to serious or catastrophic consequences immediately or down the road, but Gheesh, is it that big of deal to get more wood and get both tires completely supported and not ready to fall off the stack / have the stack collapse?

What does a "lift manufacturer" have to do with it? We're not talking about the axle, we're talking about tire damage. If I took my RV in for service and I saw you lift it by just the outside tire, I'd find a new service center.

Oh because I'm specifically talking about a lift that uses the outside tire to lift up the unit. You know, pretty much exactly what this thread is about. ALL portable jacks that I'm referring to use this method. There's pits, drive-ons (MUCH less common) and the post lifts I'm speaking of. You might have to spend a considerable amount of time to find a service center that doesn't use these lifts. Good luck [emoji41]
