Cribbing a trailer

another word for blocking up the trailer but it should be done right. hire a crew from a mobil home dealer they know how to do it. don,t want a northern wind to blow it off.

HAHA, hire a crew? We're not moving mountains....
It is just a trailer being jacked up and some bricks shoved under... hire a crew? lol.

I'm not sure why you NEED to crib, but storing it on "blocks" keeps the weight off of the suspension springs and tires. This reduces "sag" in the springs which comes from years of the weight ever-so slowly bending the steel springs downward. Torsion axles will still be affected even though they are sprung by rubber and not steel.
Modern trailer tires should be able to be stored and not get a flat spot, but it is best to unload them (suspend them in the air) as well.

You can support the camper at the corners, but the camper sits on the axle(s) and the tongue jack, so those points are the areas you can support the camper without altering the load bearing points.
Supporting it at the corners will cause the frame to slightly bow down where it is not supported, at the axles in the middle, and this is just a little flex that will move through the walls and roof - not a big deal, but you might hear a little creaking. Trailers flex and bend going down the road, so no worries, but why do this???

I had a tandem axle trailer, and when I would wheel it up on just the front axle I could detect that the frame was bowing down at the rear just from removing the rear axle support point, which was only a short distance from the front axle. The door would not latch as it did before because of this, and the door was in front of the axles so the whole frame bowed. This was a HILO, which most of you do not have, and the HILO did not have the wall structure to resist frame bending, but does illustrate the stresses the wall would need take to keep the frame align.
