Scissor Jack

Measure the length when fully retracted.
24" jack retracted about 25-26" long
30" jack fully retracted 31-32" long

And while buying do yourself a favor and buy Norco/BAL or something as opposed to Lippert. The Lipperts are made of way thinner material, and weigh half what some of the others do.

Before you buy, check the direction of operation. Different brands work opposite from each other.
I replaced the two on the back of our old TT only to find I had to turn the new ones in opposite direction from the old ones on the front.
At the end of a long trip, that's just too confusing to deal with!

I second the notion of buying BAL as a replacement. I replaced all 4 on mine. Also, buy the higher weight rated one if you are up to the task of drilling new holes in the frame to fit the new bolt pattern. The heavier the better.

I have the two jacks turn clockwise, two jacks turn counterclockwise as the result of a recent repair. Odd to say the least.

I would measure the remaining jacks to determine the size you need.

Also keep in mind that if you bet taller jacks, they will be wider when retracted as well. In my case this meant they stuck out past the edge of the RV.

I usually just stick the drill on and give it a quick zip...
- If it's the right way, I pull the trigger until they are down.
- If it's the wrong way, I flip the switch and pull the trigger.

I'm not sure it makes a lot of difference.
