I have the same TT behind an 05 F150 Supercrew and have been getting a similar experience. I even started with a similar vehicle that failed to satisfy, an 02 Durango with HD tow. package.
Anyway, I weighed about a month and a half ago. I found that I have only 480 tongue weight. About 120 is on the front axle and 360 on the rear. I intend to move a little more weight forward plus add more weight to my tongue. To do that I need to take out a washer in my hitch and take up one more link. If I just take the link I go way too heavy on the front axle. You however will probably get closer than I did with another link or more tilt. I encourage you to try it.
I do have a very nice towing experience now but my TT is a tiny bit high at the nose. I hope tools, food and firewood will help with that.

Love the trailer! Found it quite by accident. Looking for something new, and the dealer had just traded it in. They hadn't even cleaned it up yet. Dad and I looked through it first and even under the range cover was spotless, which indicated to me that the previous owners didn't use it much and/or took great care of it. All the cabinets were labeled with little stick-on labels which was another indication of someone was tried to be organized/orderly.
They had to check on the price and get back with me the next day as the salesman who had just traded it wasn't there, and the owner didn't know how much they put in it. THe price ended up being right, and the weight was great!
It really is built solidly, especially for a light-weight unit. I have no complaints about the quality.
Thanks for your suggestions everyone. We are leaving for Florida in week. We will be hauling minimal water, and I will load a little heavier in the front. But I don't think I am going to change anything until I see how it feels on this long trip.
