A64HD, thanks for input....I too am beginning to think that my setup, which only allows a max of 13% TW may be part of the problem....I guess problem amy be too strong a word...maybe issue is better as the trailer tows wonderful on decent mpavement.
As the TV needs them anyway, I am going to replace the shocks with Bilstiens. I expect a minor improvement but recognize that is not a silver bullet.
Hi Dan,
To add to the mystery, On my rig, I have 16% loaded TW. 1,600# on a 9,950# GVW TT using 1,700# WD bars. If I hit that perfect patch of concrete joint length, above 48mph, it will set the rig into an up and down motion that will stay constant until either the road changes or the speed goes lower. It acts like the natural frequency of the system just went off.
If you are experiencing what I do, going higher TW will not cure it by itself. And I'm on the Blisten 4600's now. The TT has Monroe Gas Magnum shocks and rubber equalizer and LT tires.
For me, the good news is, that stretch of road is ~ 3 to 4 miles long... And I only go over it once a year...The other 30,000 miles I have on this rig never had a problem.
Hopefully in all this, you can find a nuget that may help this. I myself would like to know it too. Backing off speed is the interim fix.
