Electric stabilizer jacks

Hi everyone, just bought 2016 kz spree 37` my question is when not in use, i keep it on my concrete driveway, should stabalizer jacks be up or down? My worry is perhaps too much weight 9000 lbs is too much if always have jacks down, but also worried if all the weight is bad for frame and tires if jacks are up.

    Rear stabilizers set just as if I was out camping, fridge on , water in fresh water tank and plugged in to 30A


    I know they're not supposed to be load carrying devices, but all stabs are is your basic automotive jack, just altered to fit the frame of the trailer.

    Each one of my jacks (i have 4) is rated at 3,000lbs each.

    I recently removed my tongue jack to swap it out, and all that was holding up the front of the trailer were the two front stabs.
  • Some will say to always store it with the stabs in the up position. Reason being, if a tire were to go flat, it will cause that section of frame to be lower to the ground, thus possibly bending/twisting the frame.

    With that said, the odds of having both tires go flat at the same time, let alone all 4, while being parked is slim.

    I always store mine with the jacks up. One less thing I have to deal with when putting it away, or picking it up. I park it, raise the tongue high enough to clear the hitch and leave it at that height. Its perfect for water run off, and its also all set for when i pick it up next time.
