Hard to say without seeing this unloaded, but it looks like the rear is squatting and it's taking weight off the steering wheels...a dangerous situation. That means the Lance isn't providing enough counterweight.
The Lance is entirely forward of the rear wheels. This means the front axle is at the very least some amount heavier than stock empty and probably a LOT of weight on the front axle. The only thing that can take weight off the front axle is stuff rear of the rear axle, which is the portion of the flatbed and the weight of the 5th wheel hitch and load on it.
I would guess without the fifth wheel trailer, the truck plus camper is something like 6,000 pounds on the front axle and 5,000 on the rear axle. I don't know how much weight that trailer would add...you think this is a 19,500 GVWR truck? If so, they could only have around 8,000 pounds payload left.
