Can one set the whole camper on jack stands?

But when the trailer is sitting on the tires, the weight is carried by the axle and tires. Picking the tires up off the ground requires the weight to be carried by the frame. It's like pulling a load-bearing wall out of a house, and expecting the walls to hold it up.

This is what I would do. Then use the stabilizers to further stabilize the trailer. Make sure the jacks are labeled with ANSI/ASME certification and with their max. weight rating on them. Never use RV aluminum stacker jacks to support the weight of a trailer as they don't meet ANSI/ASME standards. You may need to use some cribbing to get the base of a jack high enough off the floor. Cribbing should be wide enough to provide adequate lateral stability and extending the jack as little as possible will make it more stable.

I would never use the four corners of a trailer to raise it. You would be amazed at how much a frame flexes. Frames have droop/camber in them and if you lift the four corners, can cause the superstructure to flex too much and damage the structure. We have a very heavy duty frame on our TT and if I tighten up the rear electric stabilizers too much, the dead bolt in the rear entry door won't work as the bolt to striker plate tolerance is too tight (I need to fix that).

Point well taken...I wrote in another post concerning a leveling system:

"I'm perplexed as why some would say that a trailer frame might not be able to support a leveling system or that it may flex. Think about where the trailer axles are located. The overhang alone would surely flex the frame under that train of thought. Of coarse when you travel, there is another point of contact,the hitch, but there's still the overhang in the rear. That said, if I were to mount a leveling system, I would mount the "feet" half way between the axle and the corner of the unit. To help to keep the frame from "flexing". I'm such a hypocrite."

I would just put the jack stands half way between the axle and the corner of the unit. Considering that this is just a temporary situation to do service to the rig. :D

I had mine up with the wheels off. It was supported by the tongue jack, four jack stands in the middle, and blocking piers in all four corners. You want as much stable support as can be had. I have torsion axles so all support was under the frame.
