Jacks are OK but try to see if you can get away withOUT the kick down feature. They aren't as steady as "direct" and I consistently have trouble with a jack extending before it's kicked down.
We had a 24' with kickdown jacks. It was OK, but here's what happened:
Front jacks are so far aft that you get "rear lift" in addition to the commanded front lift.
And, the rear rails are narrow. The jacks mount close to the axle. So when you want "right lift" you also get left.
These two add up to often adding up to the coach much higher than it needs to be to actually get level. We could be on a somewhat but not extremely irregular site and end up level with a front wheel off the ground.
The old coach, the 24', had a single control for each wheel. Understanding that I didn't want to rack the frame, I used them carefully and liked that. The coach we have now (signature) runs two at a time. Personally, I don't like it. I'd rather do one at a time (or push two buttons at a time, how hard is that!) and have control. Last trip I had to give up on the jacks. I said "lift front" and one jack kicked vertical. Actually reached the ground. Other extended fully without kicking down and also would not retract. Couldn't pull it to vertical because it was too "long" to clear the ground and I couldn't get any perch to pry it retracted from. It's still extended. I used blocks. Still have a stuck jack to free up.
On a new coach, adding jacks rolls into the financing, maybe a dollar or two a month. Used coach, if one has jacks I'd probably buy it over the one that didn't. But I'd be hard pressed to spend $3000 to add them.
