proper weight distribution

I have a 2015 chevy colorado z71 with the towing package of 7000 pounds and 1500 pound payload. My new microlite 21fbrs is under 3800 pounds dry. the dealer set up my hitch with 2 links left at end of chain on wd bars. it is a bouncy ride. I tried with 3 links left at end of chain and it seemed better. is there a way to fix the bounce or is it normal. the roads were not perfect and it is mainly at slower speeds. I got it weighed but don't have numbers with me. Thank you for help

If you have already weighed it with the truck solo, trailer attached, and then trailer attached with the WDH spring bars in place, those figures would help here.

The other way to tell if the WDH is setup correctly is to take both front and rear fender measurements with the trailer unhitched and then hitched up........without moving the truck.

A picture of the setup is always good.

The links left hanging is not as important at the links used between the spring bars and snap up bracket. Many manufacturers state a minimum, so that the bars have plenty of "swing".

The front end should be the same height loaded and unloaded is a good start.
My set up for example no camper Frt end 36 1/2 inches and with camper @ 37 inches without WDH and using 3 links the frt is back to 36 1/2 inches.

Install some Timbren subbers in rear will reduce the bounce and also more stabization for sway. Cheap and easy to install. Later RJD

so if i go to the scales and set it up with getting weights with and with out trailer would I need to be prepared to adjust ball height on hitch or would the chains be all the adjustment I need? if so what torque do I torque them back to? I noticed I have two holes in the shank of my hitch (the part that goes into truck receiver) I have it in at the furthest in position, would having at the other hole(further out of truck) help any?

Sorry for the dumb questions I just want to be safe for my trip to Ohio at the end of the month. It has been decent to pull on the 3 local trips so far but just worried about the 8 hour drive. Thank you for the help

You stated in your 1st post that you already had it weighed ??

If you need to weigh it, make sure you weigh the truck without the trailer ( you can usually drop the trailer in the scale lot), truck and trailer with the spring bars in place, and truck and trailer without the spring bars in place. Make sure all cargo and passengers are in the same position each time. When using a sectioned scale, make sure each TV axle is on a separate section, and the trailer axles are on another section.

If the trailer is riding level, the ball height will probably not need to be adjusted. However, the head assembly may need to be adjusted to keep the minimum links of chain used between the spring bars and snap up brackets. If major adjustments are needed, then you may have adjust the ball height once you get the weight distributed correctly.

The torque specs should be in your WDH manual.

Probably not. Extending the shank might even give you a worse ride.

Is tounge weight right? Too little will cause bouncing as the tt rocks back and forth on it's axle in stead of always 'leaning' on the truck.

truck WB is also a factor. we moved from an expedition to a 4door pickup, added nearly 24" to the WB of the TV, changed nothing else and it made a big improvement in the ride.

also, what tires are on the TV? Properly inflated? P rated tires vs E rated will bounce more (less air, 4 ply vs 10 ply sidewalls)
