I initially posted this response in the "help with the forum" section, but found that you're posting the same general question (where are my low point drains?) in multiple threads. So, I moved it here, where it's more appropriately located.
I don't recall ever seeing a thread "specifically" addressing the location of the low point drains on a 2004 Laredo 28+bh. That said, here's some "general information about ALL trailers:
The low point drains are under the trailer.
They are typically located in the SAME location.
Normally, they extend about 6" beyond the bottom covering.
They will either have caps or valves to prevent water from draining while the system is pressurized.
They will be located UNDER the location of the plumbing runs above the floor.
That means they will probably be along the perimeter of the trailer, often OUTSIDE the two main frame rails.
Look between the frame rails and the side of your trailer, often just forward of or just aft of the wheelwell. They may, if outside the frame rails, be EXTREMELY difficult to see, often positioned adjacent to a steel outrigger, partly hiding their location...
All that said, if you're not the original owner, you likely don't have knowledge of specific repairs or modifications that were done by previous owners, so there's a remote possibility that a previous owner may have "cut them off, capped them and sprayed expanding foam over the caps to permanently eliminate them. I wouldn't suspect that to be the case, but it is a remote possibility.
I'd suggest parking the trailer on a concrete slab (think parking lot if you don't have a solid surface at home) and getting on a creeper. Armed with a flashlight, "roll around under your trailer, inspecting and taking note of what you find". While doing that, check the back side of the tires, the spring hangers, the springs and U-bolts, the axle tubes, the underbelly for damage or deterioration, the brake wiring for proper routing and secure connections, the outriggers for damage, the wheelwells for that same (obvious damage), any holes in the frame rails that could be closed or sealed, check the stabilizer jacks for damage, the propane system for damage and security, and don't forget the rear bumper and it's attaching points for rust, cracked welds.
ADDED: I'm including a few photos of what you MIGHT find under your trailer:
