scissor vs stab jacks
What is the advantage/disadvantage of one style over the other? My FunFinder has stab jacks and I'm not a big fan of them although they work fine. Is it worthwhile to switch?

The scissors jacks are usually able to support more weight. And it doesn't matter how far they are opened.
The other jacks are set at an angle to the ground, and the weight they can support depends upon that angle. I saw a graph (Ultra-Fab IIRC) showing that one of their jacks could support 6000# when fully extended (almost vertical) to 30", but only 3000# when partially extended to 15", or something like that.
I've never bent a scissors jack, and have used them to lift a trailer to change the tire. Trailmanor said it was OK. So, a few turns at the rear, a few turns at the front, repeat. Of course they were 5000# jacks each.
But I have bent my fancy electric stab (?) jacks on the heavy new trailer, and am wondering if I could replace them with a set of four electric, geared telescoping jacks like my tongue jack... Well, maybe not.
