Thanks for the info. Ron
I got the 25/50/25% distribution from another RV forum. I agree with what you are saying. Our spring bars are undersized and I just received 1200 lb bars and will go through the setup procedure again. The weight distribution between axles should vary somewhat depending on the length of trailer and wheelbase of the TV and I think also the spring rates in the TV (ie, 1/2, 3/4 or 1 ton). I'm hoping that the 1200 lb bars will help reduce the bounce in the rear of our trailer.
I do seem to have one odd problem. Have set the cam arm brackets 19 3/8" as per the Reese instructions but the end of the threaded shaft is too close to the bolt on the bracket. Depending on how many links I have in the chain, I can't move the shaft far enough forward for the cams to sit correctly in the crook of the bars. Not sure why this is happening. The coupler is at the top of the A-frame so nothing unusual there. I may try moving the cam arm brackets forward slightly and I don't think there should be a problem with this.
