Supporting Slides
I have a 2017 Montana 3810MS. I’m trying to eliminate some of the movement when we are parked. I’m thinking about using supports on my slide outs to help. I’m just wondering if this will damage my slide outs.

The slides are made not to need the supports. Also, if you have supports under the slide and you have a tire go flat, it can be very expensive as the weight for that side is now transferred to the slide and usually causes a good amount of damage. To alleviate some of the movement, try putting blocks under the hydraulic jacks so they don't extend so far, using X-chocks and some even use a pin box tripod to get all of the shake out. However, if the unit is still supported by some weight on the suspension, it will still move some.

Also, take a look at the X-Chocks. They really took out the extra movement in my old TT. Haven't used them on the new 5er though.

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

Yes, slide supports are a risk for slide damage. To eliminate movement in our rigs, I carry blocks I place under each leveler leg to minimize the extension distance of the leg, and have found that helps significantly. Found the pinbox tripod to be of little value.

Agree with Mike. We carry blocks and lower the front after we unhitch before we start auto level. You do have to have it a little front high, but not near as high as it is to unhook. We tow pretty level, but to get the pin out of the hitch on our truck (with automatic air bags) we do have to raise it a lot more than it needs to auto level. I put the blocks under and then lower it to a good start position (you do have to experiment with this) and then hit auto level and walk away.
