ok,
I believe the previous owner had a large truck(like a mac truck or something) because of the following mods. one mod is, he added air ride to the rv, I think he did a spring over and added the air bags, do any 5ers come with the springs on the top of axle or did he for sure move it? I will take pics the next day I can, also when adding the air ride he converted the brake system to air as well, it seems like he removed the electric component that pushed the rod into the brake hydro master cylinder. there is an air booster mounted to the hydro master cylinder, so when the brakes are applied the air pushes the rod into the master cylinder witch in turn pushes the brake fluid to the calipers. I know I want to do away with all air on this thing so dropping the bags and air booster will happen first. the part im most unsure of is the axle position(did he flip the axle or move the perches how can I tell if the axle is upside down? there is no bow in the axle. it has a brace welded to each axle keeping it straight

If there is no bow in the axle then there was no design built in for caster/camber on the wheels - should be ok either way - if he flipped them it was more than likely to lower (or raise) the ride height. It's also possible that he's straightened the bow out purposely, based upon your description of other work the previous owner has done. :-) Do you notice unusual tire wear on either the inside or outside face of the tires?

Axle will have a pin on them that will go down it sits in the plate and the U bolts go through the plate that pin keeps the axle in line and prevents it from moving out of line.

I have not seen a mod like that looks like it would catch everything in the road that passed under the axles

It looks like that from the pics you can see the curve of the axle going upward instead of downward it has been turned for sure.

A trailer axle SHOULD be arced upward.

London Aire was a heavy high end coach. Likely one of the nicest available in it's day. It wouldn't surprise me to find out it had an air suspension of some sort as an option, and pretty sure they all came with shocks.

The axle reinforcements shown in the pics would bother me. Knowing what axles cost, if I were planning on using this coach a lot I'd replace them. In the grand scheme of things it's not that hard or expensive. That's me though...

^^^^^^ THIS. Replacing the axles would also give you the opportunity to get to a modern electric drum or electric-over-hydraulic disc braking system. Axles are relatively inexpensive in the grand scheme of things.
