@Remington - No, good advice. I have a 14' tandem axel trailer - I think part of my issue is when I got the trailer under a load it would vibrate a little between 50 and 60mph. Having only trailered a couple of time previously I thought it might be how I had the Honda positioned on the trailer.. so I tried moving a little forward, a little back, I upgraded the straps to Mac's incase it needed to be secured.
I ended up taking back the trailer to the dealer (I was going to ask their suggestion) they got to looking at and said it was a bent spindle (that they fixed for free).
Now a sometimes still get a little vibration (to me it is like a wheel might not be balanced correctly) in the same range but that defaults me back into shifting the load again... this vibration is not as consistent and definitely not as noticeable. I am taking my trailer back in prior to Takeover so that I can get them to check it over/help find a potential short with the brakes as I am not getting feedback (dash gain) when they are applied.
now I try and position my rear tires where they are just over the back tires of the trailer. not sure how noticeable in pic below (and it may be a little back here
