But I do know this for a fact.

My first 5th wheel had the fresh water tank near the front and the waste water tanks in the rear. Rear bathroom unit.

After dry camping for several days when fresh water tank was near empty and waste tanks near full the trailer would not tow well and it did what I would call chucking.

If I would stop and dump the waste tanks and fill the fresh water tank (which significantly increased my pin weight percentage) the trailer would tow like a dream with no chucking.

^^^^ This is a big part of it ^^^^^
My FW tank is forward of the axles as is the Black and Grey for the shower bath, Galley is at the rear.
With FW full the 5er has very little chucking. Pin weight, actually lack of enough is the biggest cause.
That said the other factors are the ability of the suspension to absorb bumps!!
Good shocks on both the 5er and TV, 5er level when hooked to the TV!
The little bit of chucking I still have could likely bet eliminated with a Mor-Ryde pin box.

This gets me thinking...going to our destination, the fresh water tank was full (rear of axles) and the black and grey were empty (front of trailer). The chucking was pretty severe. Coming home, the fresh water tank was down about a 1/3 and the black & grey hadn't been dumped yet. The chucking wasn't as bad on the return trip...I even remember commenting to my wife that the road home must be a little smoother because the jerking didn't seem as bad coming home! Hmmm, you might be on to something! I'm going to empty the rear tank, put some ballast in the front end and take it for a test drive.
