Rear of camper sagging

Like the title says, my camper is canted back on the truck. Is this normal or is there something I can do? The truck sits almost dead level, but the camper relative to the truck is my concern. my camper does have a CG of 39", so behind the axle. I'm suddenly reminded of how I struggled to post pics on here, been a while since I've logged on.

Put a set of Timbrens in the rear suspension.

I meant your front suspension torsion bars cranked up which I presume they are not. IE you didn't "level" the truck/lift the front by cranking T bars or installing offset keys.
You're just tapped out on suspension and weight IMO and the combo of rear suspension squish and the fact that it looks like you're taking a good amount of weight off the front axle (them old Chebbie duallies don't sit near as high in front as yours looks in the pic).
Plus the front half of your truck is considerably lighter weight than newer rigs, especially diesels. WDH is going to work harder to transfer weight with the handicap you've introduced (long hitch extension).
Most folks with a 11-12' super heavy camper with slideout(s) and a big trailer behind have alot of mods on a newer dually 1 ton or are in the class 4-5 category for trucks.
Only suggestion I can think to improve the visual attitude is add springs in the rear. Not more blocks.

I'd say 1/8" over a 6ish foot gap decently centered between the axles. The rear really doesn't sag but 2-3", enough to get the overloads fully involved. It's the front that lifts without cranked bars. I'm thinking I'll decrank to get it just level when fully loaded. I may be able to find a smidge more crank in the hitch as well, but at the current stance I'm maxxed. Can barely get the chain on the frame dealie, but the bigass handle Reese gives you is more than enough to load the bars with little effort. In fact, when I last set the hitch the trailer moved when I honked on one of the bars, so I figure they're probably doing their job halfway decent. Tough to limit the front rise to 1/4" when the hitch is sitting on a 4 foot extension. Funny thing about how the truck drives: empty it tracks straight, but load it up with camper and trailer and now suddenly it pulls to one side, much moreso when your foot is in it. I aligned the truck myself, gave it -.5 degrees of camber, maxxed caster on the side that gave the least, and matched the side that would give the most until the truck drove straight. This method works great on my 1500, but this truck has always pulled to the right in 1st gear when fully loaded. I never bothered with the alignment until this year, and now that I feel it's correct I have to wonder if I have some cross-KPA going on. Aside from the weird pulling, the truck drives nice. In total control, no wiggling, no white knuckle and still stops all the weight I hook it to with confidence. I'm thinking I'll just cave and take it to a shop to put on the rack and get all the numbers as they can see more than a camber/caster gauge and a set of toe plates. There are just so many garbage shops out there though that's it's damned difficult to decide who to trust. My steering wheel is actually straight when unlaiden driving down the road which is more than I can say for the folks who take their cars to Firestone for a POS alignment.

The camper does look a little canted to the rear, but either it is or it's not. Measurement of gap between bed side and camper the same front to back? Is bed the same depth f to r? Pretty sure it is on those Chevies.
Could be a bit of an illusion because the whole setup is pretty @ss heavy and looks like it's taking weight off the front unless you have the torsion bars cranked up.
Guessing it's sitting pretty deep into the rear springs especially if that's with an additional 1" lift.
What matter is how it drives. It just looks like that big camper combined with the trailer weight is really heavy.
You said it's @ss down 1/8" in what, a few feet?
Multiply that by 8 and its an inch, maybe more with the trailer on.

I'm not worried about the truck sitting a smidge ass down, which it is. I measured the section of frame running under the cab, about a 1/8" differential there which extrapolates to more at the far ends of the truck and even more at the rear of the camper. Rather, camper to truck angles are my question and this pic does a terrible job of showing another body line near the top of the bed that better captures what I'm getting at. I'm looking now at that door body line relative to the road and feel that makes it look worse than it really is. Unless the truck really does need to be perfectly level for an ass heavy TC to sit just right?

Don't look at the fender gaps. They're not accurate. The fender lips front to rear are inches different when compared to the body lines. Again, that pic doesn't convey camper relative to truck bed very well, especially as small as it showed up.

This pic doesn't show it well, will have to snag another tomorrow. I can't tell if it's just my imagination or what, but with the truck sitting less ass down the camper seems to behave better. I may need to endure the asspain of swapping this 1" block for a 1.5" block and longer u bolts to get it perfect.

at any rate our 01 top of the bed sides to floor is about 1" deeper at the front than rear. Straight on looking from side it appears to be sitting off level. Gap between bed rail and camper wings tapers though opposite of what your describing,
Is this a recent observation that wasnt before?


Always been that way, but I leveled out the truck with a block recently and was hoping that would help. I'll measure rail height to make sure it isn't just an optical illusion.

I tried cheating by using the link to the pic I uploaded at GMT400, now I know that isn't a viable COA.

Mine's not quite that bad, but it is a good example. My concern is that the load isn't being spread out evenly over the camper floor. That and I don't like the way it looks. Makes me wonder if I'm doing something wrong or is there some structural compromise back there?

On my aluminium bed I noticed that even the bed is like 8-4" long, the ribs ends at 8', so that would be last support for camper and with 5000 lb sucker, I believe the ribs can flex on pivoting point.
So I cut 1x4 board and shaped holes to go over bolt heads that bed has at the end for additional support at the edge.

I have seen a couple Lance 1130's that looked weird on the truck as the op mentioned but nose up...All have been on 8' beds but most others don't look that way..

Just an example..
