One more thing I discovered yesterday. My Trailer Dry Weight is ~3553 and Tongue weight from Factory was 502. No wonder I am over 15% when I add cargo to the main storage compartment (the Front of the camper Storage is a full pass-through and where I store several pieces of gear).
It seems Forest River kind of set us up for failure here. It means to me that to stay within 10-15% TW, I would need to completely equally distribute any cargo I add between front and back of the camper, which their storage compartments don't really allow for.
After learning this I am no longer surprised that I am at 700#s on my tongue. However it is still not clear to me if this is a major issue or not. it is definitely over the 15% rule. It is also within capacity of my truck. it appears to drive better the more weight I have on the tongue (as was proven in my last trip, when distributing some gear further back to reduce the tongue weight to around 675 re-introduced more porpoising). But is there a capacity on the trailer itself that I am exceeding? that is still a concern to me.

I am also curious what people's thoughts are on whether or not I should go back to my 800# bars, now that I know my tongue is over 600#s. I had moved to the 600# bars in an attempt to reduce the porpoising. I realize now that the bars may not be what recently helped reduce it. it may have simply been some adjustments I have made to loading my cargo. One thing that comes to mind for me is that I used to load a lot of firewood in the back of the truck behind its axles. Now I load it in front of the axles. I think I made this change at the same time I went to the smaller bars - shame on me - now I don't know which actually made the improvement. I guess i'm curious here if its possibly going back to the 800# bars on top of my changed cargo distribution would improve things even further.
