I think to get good weight distribution, chains should be tightened with no load on hitch ball, then lower trailer jack to put load on the ball. Will settle to desired trailer and truck level as jack continues to its store position.

Trailer perfect level, truck down 1" in back and up 1/2" in front. I'm okay with that. Handles nicely, quiet, couldn't induce sway moving steering side to side, trailer just followed.

Trailer has 16" Michelin LTX M/S LT225/75R16E on Sendel T02 wheels.

OK, took me 15-20 minutes to refind post number #764. So am posting it here for reference (or until all the "engineers" bury it again. lol). I have ordered my replacement trailer cord for the one I ruined drilling for the setscrew. Good thing I pulled and measured it...it is 10 feet long! So now I want to finish my Anderson hardware install before reinserting the cord back in the frame. I have the bottom set screws in already. I have a 4" 4 sided frame, which it looks like dkottum has also. I just need to add the top bolt. My brackets already have the extra hole.

So dkottum is your setup still working for you? Any advise before I start drilling? Note, I did get one of the first new tilted brackets, so I plan to mount it straight up. Any advise appreciated.

Rich,
I mounted mine exactly like the instructions said. I did look at it tilted back at the top but went with the instructions saying mount straight up and down. . I used the set screw with a slight indention drilled in. I have had no issues with the hitch or bracket slipping.

Rich, that photo is my Tundra for a short time, I now have it on a Ram.

My frame is 5" (actually slightly under which allowed me to tilt the brackets). I assume you have the 4" frame brackets, or should have.

Before you drill, using the Andersen bolts tighten the bracket tightly to the frame, ensuring the most direct angle of the chains. The trailer should also be on the hitch so you have the right distance to set the brackets back (if you screw this up not all is lost, you can lengthen or shorten the chains).

Do all your drilling, or at least start the drilling with the brackets firmly bolted to the frame or you may have trouble with bolt hole alignment when done.

I predrilled the outside bracket in the drill press, installed it all, drilled through the frame so as to start a hole on the inside bracket, took the inside bracket off and finished it in the drill press.

Then assemble it all, turn the outside set screw tight to make a mark, remove the set screw. Drill a hole for the set screw smaller than the set screw itself so it will not go all the way through, then install the set screw.

I could not get a drill behind the frame to drill for the inside set screw, so I just tightened it as tight as I could.

Take your time and think it through as you go.

Before final assembly i touched up all the bare metal with paint, and sprayed it with CorrosionX. The brackets have not moved in 3700 miles.

Yes, that would be ideal.

Custum brackets

Version two of my custum brackets. Three and a quarter inches longer, two set screw and paint at the same color as a frame. With this setup, I should not have wear and the force on the plate will be strait.... It is, however, in this spring I'm going to give you news ... Sorry for English ....

Tino, those look great. I think the square tube will work out to be better than the round. You have some nice metal working skills.
About your English, it is much better than my French. So you certainly have nothing to be sorry about.

It's probably me being anal about it but when I installed my brackets last month one of them somehow was off a bit. Don't know how these things happen but it couldn't have been my fault. It was off about 1" or so from the other side. Yeah, I know it really doesn't matter and I can adjust for it easily but I just felt better correcting it. Today being such a nice day I made the correction and feel so much better now. I had only taken it for a test drive at the time of installation but in Feb. we'll hook up and head south for awhile so I'll get a better feel for it at that time. I think I'll have to remove one link from the chains but I will wait on doing that.

So, I don't need to lay awake at night worrying about this job. It's done.

Oh yeah, and Tino, no apologies needed here. You're english is much better than my french. Your welding skills are very good too. Nice job.
And we've enjoyed several trips to visit Quebec over the years. Love that town.

Unless Andersen had a count difference in the number of links on each side I can't envision any way you would have to remove a chain link if the brackets are set back to equal lengths on each side of the A frame.

Remember while Andersen suggest that equal displacement be maintained on each Acme screw that is only a suggestion and not a requirement as the hitch will self center against the combination of tension on the chains as you drive.

Unlike other WD hitches the Andersen applies the WD force along the center line of the hitch rather than the offset per bar that most bar systems are design with.

Thanks guys, for the feedback. My frame IS 4", but the brackets have extra holes for a 3" frame. My thought was to drill through the extra upper holes and add bolts there in addition to the set screw holes to keep the bracket from tilting back under tension. I was set to get some extra 5/8" bolts and nuts for those holes. Upon closer inspection, however, I see a couple of problems. For one, that puts the extra bolt holes very close to the upper edge of my frame. But the bigger problem is that there is not enough room for the heads of the bolts or the nuts to turn with both holes having bolts at the same time. So I could drill 2 smaller holes at a lower point like you did, dkottum, but the bracket material is much thicker than my frame steel and I don't have a drill press to use. So I think I will just drill the set screw holes (one left to do) for now and try that before going any further, as you did, AirHeadsRus. Unfortunately, there isn't enough room on the inside of the frame to drill, so those set screws will just have to be screwed in as tight as I can get them, without the drilling. I have already mounted the brackets while hitched up, and I have them so the upper bolts are gouged into the frame material. Hopefully, the set screws will be enough to stop slippage. I will leave some masking tape in place so I can check it for any slippage.

And that force is applied with a "spring" bar lifting vertically to apply tension. The Andersen chains pull back horizontally eliminating the spring bar.

This is a feature of the hitch that would make it difficult for me to return to a conventional w.d. hitch.

Every few hundred miles with our Equal-I-Zer we would come onto an old segmented concrete highway or uneven pavement that would send pitching and porpoising moves through our truck and trailer. Sometimes so bad we would have to slow or find another route.

I have not driven those same routes yet, but in 3700 miles around the country we have not experienced that porpoising with the Andersen.

Hi Howie. Hope the " storm of the century" didn't make too much of a mess. Personally I came out pretty much unscathed but around us was trees all over the place. My son lives in S. Brunswick and had 2 come down. Lots and Lots of firewood for his wood stove.
I know what you mean but I think I mounted the brackets just a tad too close to the ball and had to crank down on the chains to get the proper compression. I could move them back an inch or two or remove a link from the chain. I will take a look at moving them after I put a few miles on it and see how it rides. And yes, the thread count was different on each side. No big deal but I just wanted to keep things balanced.

My view.....

Conventional WDH's are more sophisticated compared to the Andersen in the way they transfer weight to the front axles. There is more going on than just lifting the rear of the vehicle. There is a very effective twisting/rotating motion that occurs in the hitch head with the torsion bar design.

The Andersen uses a simple lever system that is only linear but does results in some weight transfer. The Andersen design appears to be less effective.
