Trunnion bar dimensions and angle

I pull a 1960 22' Safari with a 2004 4WD Tundra. I just bought a used set of Reese 500# trunnion type WD bars to replace the (too stiff) 1000# set I have been using. Now I see that the 500# bars are shorter (28" vs 30") and the forged heads seem to have more angle, so that the bars hang very low at the back ends. I'm not sure if I can tilt the hitch head enough to get the bars relatively level.

Do the trunnion heads come in several different angles? Is there such a thing as 500# bars that are 30" long? Moving the brackets on the tongue would cause them to interfere with the LP tanks and battery. The bars I have mentioned are the older type, without the bend near the small end.

could you get shorter bolts fro the brackets so they don't hit the LP tanks?

There is only one trunnion for each of the 3 bar ratings.

You can tilt the ball mount to make angle changes.

The chain, from the bars, must be absolutely vertical.

However, if you add the straight line sway control then the chain angle is not important. That would solve your problem with the hitch.

I took the time to move the brackets on the tongue by modifying the battery mount. Now the 500# bars fit just fine, and the ride is much softer than before.
