Question Determining if axles moved?

So, bear with my hand-drawing here since I'm not at the camper to take a picture:

Name:   Wheels-Wheel Chock.jpg
Views: 336
Size:  19.3 KB

In this:
- the yellow is the road
- the black are the tires/wheels
- the red/pink is the wheel skirt
- the green blobs are the wheel chocks

When we got setup at one of our stops, we found that it almost seems like on the passenger side, the wheels are sitting higher up under the wheel skirts than they used to be. Meaning, the triangle of space where the between-the-wheel chock (RotoChok) goes in has gotten smaller.

It was usually fairly close, but cleared just fine. Now, I literally have to pull the wheel skirt outward a bit to slide the chock up under the skirt to get it between the upper part of the wheel. The driver's side still fits like it always did.

Unfortunately, I'm not where the camper is, but, I am thinking that I'll get under the camper and try to measure from somewhere on the axle to the frame on either side and see if they match. If they're different, I'll try to look for anything on the axles that looks amiss.

I've pulled it a good 1,000+ miles like this and haven't noticed anything different with the towing experience- but it definitely doesn't seem right.

Thoughts?

Since you have a 5th wheel, you should try and get your camper weighed with emphasis on the load on each camper axle.

Your aft wheel set (rear axle) could be carrying more of a load than your front ones. With Torsion axles, this will result in additional deflection of the rear axle and your tire spacing will decrease.

He has spring suspension and the equalizer walking beam.

I do have a spring suspension and this "equalizer walking beam" - is that the Lippert EqualFlex suspension?
Equa-Flex - Suspension Enhancement

I know that the one time I weighed my axles split on pads, they were within 20 pounds of each other. I can weigh it again, their is a scale house about 15 minutes from here that I've used before.

I guess my original hope for this post was suggestions on what/how to measure or specific things to look for.

Passenger side of the road can be a bit rougher - so the springs on that side may be getting soft, bent, or there could even be a broken one.

Have you noticed this at multiple locations or just one?

Multiple locations. We saw it at, at least, 2 or 3 different campgrounds and on the road in front of my in-laws house.

I am certain that the camper and axles (collectively) are not overloaded- even with the weight of this last trip. Believe it or not, I actually weighed mid-trip when we moved from Florida to Alabama (just a single weighing of truck + camper).

I would look for worn shackles, shackle bolts, etc. If you do not have "wet" bolts (those that can be lubed), they can be worn and should be replaced with "wet" bolts. Look very closely also for a broken leaf in the springs. Also measure from eye to eye on all the springs. The measurement should all be within 1/8" of each other. Measure with the wheels on the ground.

I also have these other pictures from last year when I changed the tires on the camper:

Any chance that the side where the distance between the wheel is less was pulled up on blocks to level? I noticed the same thing when pulling onto the blocks...the center link allows the axles to move fore/aft when making that kind of maneuver or turning. From what I've read in the LCI instructions for Correct Track alignment, the camper has to be on level ground. If the camper was backed up, it has to be pulled ahead at least one full tire rotation before alignment of axles can be checked.
