Here are the specs I found on the trailer:
Hitch Weight:2665 lb.
Exterior Length:43' 3"
Exterior Height:13' 4"
Fresh Water:83.00 gal.
Gray Water:123.00 gal.
Black Water:41.00 gal.
With that much trailer, your loaded pin weight will be around 3800#. I sure hope you have a 1 ton DRW truck.

Well I would have the alignment of the trailer axles checked to make sure they are set correctly.
It is nice to have a 3500 DRW, but you are pushing the tow rating of the TV, at 18,000# for the 2012 unit.
I would also look at the Yellow Payload sticker for inflation for the front and rear tires, likely 70 psi to 80 psi fro fronts and 65 psi for rears, if so try dropping the rears to 65 to 70 psi.
That said with ONLY a 2,566# payload for the 5er, it may be heaver than 18,665#. The real pin weight is likely between 3,733# (20% of GVWR) and 4,666# (25% of GVWR).
I would suggest a trip to the scales to see how your weights are, especially, pin weight and 5er total weight Pin + axle weights.
