Thanks to all who answered. I decided to retract all my electrical stabilizer jacks while the trailer sits idle next to my house. Coincidentally, when I went to retract the left rear one, it was stuck. I used a ratchet and socket to turn the nut, but after a thousand turns and no progress, I got my drill and it retracted quickly. Lesson learned - if you have power stabilizers, carry a drill in case they get stuck.
The posters who pointed out that the jacks will be damaged if a tire goes flat have a very good point. Also, I noticed that trailer dealers store all their trailers with the stabilizers up, often for very long periods. In summary, no good reasons to extend the stabilizer jacks, but reasons not to.
Any one afraid of getting a flat tire while stab jacks are down and parked should just unload every thing from their rv and sell it right now. The slight drop will be about 2 inches the most before rim hits the tire and tire compress against ground. If you pull the trailer down the road at all there is much much more strain on frame with every mile you drive and that is constant. These frames will not crack from being parked and a flat tire shows up. They flex more than you think from just hanging in the air and good reason to use stab jacks when parked.
Mine are down when parked. We use our trailers at home as well...
I also have my OFF-ROAD POPUP usually with beds extended all the time. It my man cave haha... I have my own little camp site setup near the woods at the back of my back yard... Bonfire going every night...
