I’ve done it without problems but unless it’s raining or something I’ll put LEGO blocks under wheels that would otherwise be off the ground. When I do that I also put a similar number of blocks under the adjacent jack just so they won’t overextend.
I read on another post that some jacks that rely on springs to retract can have trouble with the added weight of snap pads. Apparently they are surprisingly heavy! But it doesn’t seem to be a widespread concern. I’d buy then if they cost a bit less! And may anyway if I ever knock off my long wish list.
Snap pads only weigh a couple of pounds each at the most. Jacks that rely on spring retraction have been problematic for many owners, the springs weaken over time, the cylinder jacks gets corroded, the hydraulic oil gets old and dirty, and the jacks just don’t want to retract anymore.
I went thru 2 hurricanes while living in our previous MH on the east coast, had the jacks down, front wheels off the ground, never had a problem. That said, your results may vary.
I have had my SnapPads for a couple of years now, wouldn’t hesitate to buy them again, recommend them to a lot of people.
