I think that would be a great idea, but I think the mounting holes in the flanges/plates are punched out [not drilled], then the flange is bent to the standard shape. It might be possible to get them to omit the punching out of the holes, and just bend blanks, but I bet it delays the order for weeks, if it's even possible.

Leaving within the next 30 minutes for the Dexter dealer 178 miles away. Let you know if the it's possible to get the flange with no holes.

My brackets

Zep,

Here's a pic of my brackets. The guy said they were low profile, what you think? I did get reversed brackets.

Thanks, Michael

Holy cow, you're right. They are low. Learn something new every day. I guess I'd check and see where your belly pan is. If there is an inch of space from the top of the axle slot up to the pan, then I'd still get the high hangars. But you're there and I'm not...

Last year, we replaced the axles on our 28 ft Ambassador with #3500 Henschen's with 12 inch electric brakes - replacing #3200 rated axles.

The new axles as received from InlandRV were exact fits, without any mod's needed - they bolted right in, and couldn't have been easier...

While jacking the trailer front and back may be an accepted routine, I'm not sure I'd want to do that on an older trailer - having to depend on all the rivets in the outer skin to keep things intact... Why temp fate with all that 'flexing' when you can easily lift the trailer as per the below routine...

I simply ran one axle up on blocks to then replace the other - supporting the trailer on it's normal axle loading points...then running the new axle up on blocks to replace the other - this method, when the AS remains hitched to the TV, safely elevates (providing you use suitable blocks, of course) the trailer so you can work under it without worrying about jacks, etc...

Our AS is a bit over 6K with all our stuff aboard, and rides so much better than with the old 'sagging' axles, it's hard to believe...

Estimating axle gross weight

Turns out I was a little shy in estimating what axle I should have ordered. The trailer weight is correct, but it turns out you DON'T want the axle max load to equal the trailer max weight. You want about 30% margin. These axles do OK for the Overlander, but I just did some research on new axles for a '73 Safari. The original axles were spec'd at 2600 lbs. The dry weight of the trailer on the wheels (not including tongue) is 3640 lbs. Max weight with water and stuff won't exceed 4500 lbs.

Current recommendations for this trailer is a pair of 3000 lb axles! That's a 33% margin. I thought it ought to be more like 2400 lbs, in order to get a soft ride. I caved and ordered 2800 lb axles.

Zep.

The soft ride can be obtained several different ways, or a combination of them.

Reduced tire pressure (within reason).

Softer torsion bars.

Lighter suspended tow vehicle.

Balanced running gear.

Basically, the axle rating can be increased 10 to 15 percent, without having a negative impact on the softness of the trailer ride.

Of course, the huge unknown factor, is the "pay load" that some may choose to carry. That can become a huge variable.

So far, all your projects look great.

Keep up the great work.

Andy
