Frame Stiffing to reduce Porpoising?
Got a question for you seasoned drivers with older rigs. I have a 1999 F350 Dually Quad Cab Long Bed. I've been driving it for thousands of miles and for the most part, it's been fine. However, while ...

Meh, the funny math doesn’t really prove anything.
Especially since you’re speculating about 2 out of the 3 weight factors. People and stuff and actual camper weight.
$20 says your 7600lb truck, camper and everything in/on the truck is right around 13klbs.
Maybe 12,500.
I’m not saying I wouldn’t haul it. Quite the opposite in fact, but you’re arguing with yourself again, now trying to prove how light it is I guess? after starting the thread about how heavy it is!
Sometimes these things require one to do a little easy real world information gathering. Like weigh the whole thing and don’t be forgetting anything.
Although what it actually weighs is largely immaterial except to settle the speculation.
And measure the deflection if it’s worrisome (which you also said it’s not, but a definite annoyance). Easiest idea I can think is tape/attach a crude dial indicator to a vertical surface between the camper and the back of the cab at the top of the cab. Like a tire depth gauge maybe. Long enough to touch both surfaces.
See how much it compresses over some bumps at low and high speed.
From that you can do some trig and figure the max rotational angle the frame is flexing and the total amount of droop/flex.
But that is also really just a science experiment…. But better than speculation since it’s bothersome or perplexing.
