Use of supports will not improve 'jiggle'. As long as you have the tires in contact with the ground, there will be some sidewall flexing and "jiggle" will happen. Also the way any towed trailer is supported/leveled is not really a solid foundation.



I do use supports under the 13 foot long LR slide while we are at our summer seasonal but that is a cable operated slide on a HC and it will sag a bit over time along with temperature.



I would not use supports under a hydraulic or rack and pinion slide though



A flat tire will not allow the unit to list to one side if you have the levelers or rear stabilizers down in the event of a flat tire. Additionally that flat will only sink - maybe - 3 inches in a static condition but the other tire wil keep the unit level.


When we travel, I use two BAL X-Chocks. If at a CG for over 2-3 days will add a spare pair of manual rear stabilizer scissor jacks left over from a long gone TT under the frame about at the entry door location. This will mostly control but never totally eliminate 'jiggle' - a fact of RV life
