that's the plan...
Just enough down pressure to keep the tires from bouncing around ;D

Would airbags each end be even better?

Any single axle trailer is going to do the teeter totter...If not loaded correctly.

There, fixed it for ya.

Seriously though, tandems also teeter totter unless the a axles are sprung independently.  Like the trailers I've built with two torsion axles.  Or if you did leaf springs and did not use the balance bar.  Still, the trailer will teeter a little.  Only it's a short hard jolt instead of a gradual sway.  My torsion axle trailers ride pretty rough empty, but loaded to 80%+ of their capacity, they ride like a dream.  Sprung tandems with a balance bar seem to be more forgiving.  They ride better with lighter loads.  The only real solution to a teeter totter issue is to distribute the weight properly.

How much weight are you dealing with?  Or you gonna make me google the punkin to see what the manufacturer says?

Not just the Boda...there's many accessories as well as odds and ends kinda stuff...
I built all of these trailers for tight space maneuverability, so empty they are pretty neutral weight wise with fairly short tongues...This makes turning around in the woods and customers lots a breeze
I know how to correctly load a trailer, Boost... ;D
I'll tell ya what brought this on...I've been getting alot of work 50-60 miles away from home and using the 2 wheel trailers at hi-way speeds on the rouph roads around here scares the shit out of me...If you watch the tractor in the mirror too long you WILL GET SEASECK from the up and down rocking...Not swaying side to side...when I got home with the dump truck...the rear shocks were almost smoking...so they had long gone faded to shit...barely felt the difference in the cab...
I just don't want to pay the outrageous prices for the shit that's out there for sale these days

Ok, so let's look at it this way....If your trailer is loaded correctly with the general rule of 10-20% tongue weight, and it is still doin the teeter totter thing.  Then the problem is the tow vehicle.  Springs on the trailer would be a good idea, but springs and/or shocks on the truck would do more to stop the rocking.

So how much weight are we talking.....

5000# minimum
The trailer is just too short for this job...
Ya I can go over the scales locally...70 miles one way with truck and trailer at 13 to 15 thousand pounds, with out a problem...been doing it for almost 30 years...But here's the new scenario...
I may need to make 4 1400 mile round trips back to back with-out time to fook around between them...
I like the idea of the walking beam because the principle allows the axles to work semi independently without adding the height of leaf springs and shackles...or the expense of torsion axles

But when compared to the single axle you got now, it does nothing to fix the teeter totter.  That's why I brought up the truck springs/shocks.  And from you description, I think I'm on to something.

The main reason I don't like walking beam set ups, is the problems with alignment.  Especially at high speeds.  It takes so much to get it right and so little to get it wrong.  Just one trip the length you are talking could burn through a set of tires or worse.  Add in the amount of weight we are talking and that walking beam design and alignment becomes more critical.

Not that we need to know, but what's the reason for the distance?

I know what your saying about the walking beam and the alignment issues it creates,

Can't say just yet...but I need a change of scenery...

Altho I think it's a neat idea I'm thinking prolly just do a 20 foot conventional tandem axle trailer...for the move and back to the single axle once the boda and stuff are there

Why would you want to go back to a single axle? EVER?

When turning around on customers lots tandems tear up the grass
Not a problem on most jobs but there are those that I need to turn around on the lawn when working around the lake...Up here most of the roads aren't wide enough fo me to park on the shoulder without being part way on the road
Plus I'm thinking I prolly won't need such a big trailer all the time ;D
But I could be all wet here tho ;D

After last nights conversation that move may be getting much closer to reality now.
