axle recommendations

Hey folks, I've begun work on my $1 purchase. It's a 1973 31 ft. landyacht.
I've completely gutted it. I'll post a pic. anyway onto the next phase. i am in process of reinforcing the tube in order to stabilize it for frame removal. I'm looking for insight as to the overall distance between the left and right mounting perches. I'm considering mounting 2 7000lb axles under it.
I know you may consider it overkill but they carry larger bearings, have a heavier load capacity which results in less stress on each axle and lastly I can install disc brakes on them. Any help would be appreciated.

Talk to Colin Hyde, you don't need axles anywhere near that capacity to install disc brakes. I have 12" disc brakes on 3,500 lb axles.

I think axles that heavy would shake the Airstream apart.
Mounting perches? do you mean mounting brackets?

I would reccomend axle capacity not much more than your gvwr plus mybe 10%-20%. More capacity means less deflection for a given load resulting in more road shock transmitted to the trailer.

Now if you were talking beam axles with leaf springs, OK, but not with torsion axles.

I put 2 5000# axles on my 9100# Classic 30. I got EZLube axles and mounted Kodiak 12” disc brakes behind 16” wheels. I don’t think they would have fit with 15” wheels.

You better build a real frame to put on top of those axles.
