When we first got our camper I use to drive with the sun visors down,
the campers nose moves alot in relation to front of truck. Normal yes, frame flexes/twists between bed and cab but after a while you wont notice.
A rubber mat, even with the spray in liner will help alot if there is actually movement. 
As to rocking, not sure. Center of gravity is a lot higher so truck will handle/react different to any side forces. If camper is actually rocking in the bed, really not likely given weight of camper (11' under 2000#?) better tie downs could help. Unfamiliar with Brophys other than the old stake pockets. Umm I just looked, crbrophy.com I think Id start saving for Torklift or HappiJac tie downs.
I'm a she. :D 
Yea, camper is exactly 11.5' and weighs exactly 1895lbs dry. (So says the plate on the camper and the original sales receipt from the dealer.)
The Brophys are the super heavy duty ones from the link you gave.
I dont see any movement side to side through the back mirror, or even when I kept looking over my shoulder every five seconds to make sure the thing was still connected to the planet. It's just over the cab that I see it move OR when Im out watching someone else drive it into a dock. (When I got new tires.) The truck bed and camper moved in unison, but it seemed to me to be a lot. It feels STRANGE, looks strange, and Ive nothing to compare. Never watched a TC move slowly into a dock.
 Yes the liner is a spray in. I can't remove it.
It handled fine, even when big 18 wheelers drove by me at warp speed. Just "moved" a bit to the right, then recovered instantly. (but I do credit myself to good driving skills. ;) )
Yea, im terrified of being overweight. My truck is a monster. My diesel engine weighs a lot. Id just be sick if I had to get rid of either one of these beauties. The TC is spotless, never used, no rust, no leaks, no dust or mold, and the pickup no rust, pristine paint, also a beauty. Took me 3 years holding out to get exactly what I wanted, then realized I might of just made a dreadful mistake on total weight. The guys told me my truck would handle the TC. I believed them. It probably will. Ive had so many diesel mechanics offer to buy my truck while I'm standing there, so there has to be something they like about it. The guy who put in my new fuel line said I had a gem. 
I bought the heavy duty tires to increase my payload as the Ford guy told me the axle rating is based on the tires you have, so I bought the highest weight rated tires I could find that would fit my rims. They had to special order them. 
I figured my springs can handle extra weight? I wanted one of the old diesels bc I didn't want any computerized gizmos in my truck engine, and I wanted a sturdy body.
I'm just kinda freakin out. I cant afford TL right now bc my tires cost around $1000. I'm traveling to central states to see the eclipse in August, so I wanted reassurance it will be OK...at least for that trip? 
I guess I will look at happy jacks, and have someone look at it. Im so terrified to go to the scales. I hope it's not a weight isdue that makes it move. But lije I said...the bed and TC move in unison...the TC is NOT moving independently of the truck.
TL just seem so much better, but one post here said hes been just fine without them. 
Ahhhhh. Sheesh. 
THANK YOU ALL SO MUCH!!!!
