Yep, that's mine

I don't believe this is correct.
The Fulcrum point would be the fifth wheel Pin, not the center of the two axles. Adding spacers at the axles will not lower the front of the trailer(front cap). It will however, raise the entire trailer. The point that will be raised the most, is the farthest point from the Fulcgum.

I'm by no means a suspension expert.., but installing a spacer block between the leaf springs and axles I wonder what kind of added torque/forces come into play during TV turns, especially on the longer u-bolts? Without some side-to-side reinforcement considerations will the increased distance between (ctr to ctr) the axle to the leaf spring shackles be an issue during TV turns?

Just thinking out loud.

Chipper - perhaps you misunderstood my point. I was not saying that adding 2" height to the axles would lower the front. Instead, I was saying that UN-hitched, you would need to lower the front 2" to get the trailer level. That would mean that, again UN-hitched, level condition would put the pin 2" lower than the hitch socket. Therefore, raising the entire trailer at the axles by 2" would allow you to hitch up in a level condition. JMHO

The problem he is having, is with the 5er hitched to the tv, not un-hitched.

Just trying to find the best/safest/simplest option
Thanks

OK, chipper - one more try. Take your diagram. If he is 4 inches too high in front while hitched, and 4 inches too low in the rear, then raising the trailer in the center by 2 inches should raise the rear by 4 inches, assuming he is still hitched at same height. As in your diagram, pivot (fulcrum) will now be at the hitch. That should make him level.

See Quote below. The front is not 4" too high.

Although, I'll have to agree with you.
A 2" spacing(rise) at the axles should bring it pretty close to level.

Fifth wheel leveling

thanks for all the replies, I appreciate it.
I will bring the trailer in a trucking shop where they deal with that kind of stuff and get it raised. I was mostly concerned with the height I had to go to and the centre of gravity but sounds like I should not have to worry about raising 5th wheel a couple of inches.
