Yeah its definitely not a loading issue with the boat, no rollers it has bunks and its a tandem axle trailer and the axles are fixed so moving them is not a issue Its not the only trailer Ive pulled either its definitely the suspension on the truck. I might just have to order air bags, and see if that helps.

but if the trailer doesnt have enough tongue weight, and isnt putting enough weight on the truck, airbags wont do much...
nice boat btw, is the gas tank in the back? was it full when you were towing?

edit: i just noticed you said it does it with other trailers. ive never pulled any other big trailers so maybe mine does it with all trailers too. get the airbags and let me know how it works out..

Could you have a broken spring in the back?

I pull a trailer once in a while with 10K lbs and electric brakes. I thought I was overloading a little bit. You guys make me feel better!!

Can you man-handle the boat around with the trailer tongue jack/wheel in the up position? If you can, your tongue weight is way too low.

Check out this link for a way to measure your tongue weight with a bathroom scale:

(note: you can change the ratio of the distance between pipes and mutiply by the new ratio if 3x isn't enough)

The gas tank is right in the middle of the boat I've pulled it with it full and empty. I haven't really tried to man handle it, I guess I'll have to try and figure out the tongue weight.

Just by looking at that boat..Very nice..btw...It looks very centered on that trailer. I would bet you don't have enough tongue weight and the trailer is actually lifting that back of the truck over larger bumps.
Go over and pick the tongue up. If you can pick up the tongue, it's way too light.
If that's the case, you could just add weight to the front of the trailer or in your bed.
How much gear was in your bed when towing ..weight wise???
I'm just throwing stuff out there. Wingin' it...lol
