I don't know why this site is so problematic at times. Second and last try

Speaking of…what is going on with the front of the truck bed and the something that kinda resembles a cut up rear bumper for the wrong truck in the wrong location? 
Now that I think about it it’s a F550 that I don’t believe was ever offered as a pickup (unlike the 450 models which were a little different than the c&c trucks but I didn’t think that started either until the first refresh of the Superdutys). 
If this truck has a pickup bed cobbled onto a straight frame, may want to make sure that’s legit for hauling 2 tons of high profile load. Or the tiedown chain rodeo that’s going on will not be your greatest concern. 
And assuming the bottom of the front of the truck bed is solidly attached, block the camper off the front of the bed at the bottom with some lumber or sumtin so’s you camper won’t be smashing into the top of the bed and trying to make out with the back of the cab. 

Ya, yikes! 
If them 45deg angle front chains ain’t doing the trick or bending the tie down brackets on the truck, find less “extreme” trails or quit using crisco on the bed mat. 
PS they will do nothing for side to side sliding but a couple well placed boards between the inner fender wells and camper will stop any excessive lateral movement. 

That is an experiment to work with the front tiedowns to minimize the backsliding and side shifting of the TC going up steep rough hills. The framing and attachments have been reinforced so they should be able to handle any strain.

I'll keep you posted as to how it performs over the next week or two.
