Guess I'm the odd man out again.  I have a Rhino Lined bed on my F350 and over the course of 2 TC's now, they have both sat on the liner only and no movement what so ever (and that includes off roading) and off camber turns and steelpgrades on dirt roads, most of my camping is off road....
I don't have TL tiedowns.  When I got my first TC, TL wasn't even around.  I have HappyJac's front and rear, never an issue, not one hiccup.  At some point I may purchase a set of TL cam lock tie down's but HJ has come out with their own (and a lesser price point) so I may get them, not that I'm unhappy with the HJ turnbuckles, it's just the cam locks are quicker on and off.  having said that, I usually leave the camper on the truck all season except right now when I'm using the truck for the farm (to haul tractor fuel)  Once I'm done planting, the camper goes in the bed and stays there until winter, when it comes off and goes in the garage.
I quit watching my camper out the window (I have a crew cab so I cannot see the nose in the windshield )and yes it moves, but, if it didn't something would be wrong as the bed needs to move independently from the cab and the camper is in the bed so it moves with the bed.
All this phooey about TL being the best...  is, in my opinion and 20 plus years of TC experience, a bunch of phooey perpetuated by people who have never used anything else.
Happyjac was around a long time before TorkLift and I've never heard of any campers coming off the truck using them.
If there is, please enlighten me....  If not, quit bragging about TL because it's just that bragging.
TL produces some outstanding products but so does HappyJac.
