I might consider it if I was parked permanently on blocks but see it as just a waste of money and storage space to carry one now.
Think of what could happen if your tires went flat on that side or a jack failed? That extra weight would be pushing up on the slideout. Small chance of happening but not good if it did.
I agree, we don't use them, but we also have a stab jack in front of the axles which would and did hold when we had a tire go down. Had unscrewed the monitors and then had the trailer washed and waxed and when the guy was cleaning the wheels, inadvertently screwed one monitor in a little which caused it to leak over 2 days. Neighbor came over and ask if we knew we had a flat. Sure enough, flat! Had to get the compressor out an re-inflate. Now, I just take the monitors off if parked over 1 night.
