a stabilizer works well to help so of the exciting moments i also see you are funning 42 psi in the rear .. by myself i used to run 40 psi same as for 2 up be even with 2 up i noticed the wobble was worse dropped back down to 38 psi i was a lot better .. had hd check rear tire of course noting wrong and when i had it on the jack i couldnt find anything either but it sure made a difference just going up those 2 psi
