Stabilizer Jacks

by Greg Zimmerman

Adding BAL scissor jacks greatly increases the stability of the Casita. Prior to 2019, Casitas came with single leg rear stabilizers and relied on the single front jack to hold up the front. This tripod arrangement isn’t as stable as 4 corner jacks. Starting with 2019 models, Casita added rear scissor jacks, but they still leave the single jack as the only support up front.

Little House Customs sells laser cut, 1/4″ thick steel mounting plates. They are welded to the frame and BAL 24002D jacks bolt to the plates. This is nice because if a jack gets mangled (maybe by leaving one down and driving away), they can easily be replaced with a few bolts. Factory Casita scissor jacks are welded directly to the frame so replacement requires cutting and welding.

Each made-in-the-USA jack is rated for 7,500lbs. Using a pair of them, a wheel can easily be lifted to change a tire, although officially BAL says not to lift a tire off the ground. I think that warning applies only to much larger and heavier trailers with multiple axles. The Jacks come in pairs and are available here:

A local welder can easily add the plates to your Casita. If you’re a D.I.Y.’er with a welder, use a grinder with flapper disc to clean up the frame to bare metal. With the plate in place, the jack is extended up to hold it tight against the frame. The plate is tack welded, which means just a dot at each corner to hold it in place. Once fitment is verified, the jack is removed and the plate is welded in front, back, and along the outside edge. I use a Miller 211 MIG welder, which does a great job. After it cools, I spray satin black rustoleum paint to protect the metal from rust.

Each pair of jacks comes with a hand crank, which is good to keep for a back up. For primary use, Camco sells a $4 adaptor to use a cordless drill to run the jacks up and down. Zip, Zip, Zip, Zip and you’re leveled and stabilized.

Did the propane line give you any isssues?

No, it cleared just fine on ours. Some Casitas require moving the ground clamp on the propane line.

What is the optimum bolt size? Lock tite nuts?

Greg Zimmerman May 22, 2020 - 12:56 pm

The Plates from Little House Customs come with new 3/8″ bolts and nuts. You use the star washers that come with the jacks and throw away the lag screws. No need for loc-tite with the star washers, although it can’t hurt if you use blue.

Thanks for the response. I received the plates and set them aside and didn’t realize bolts were even included. When I start I should be in great shape. As a Casita owner, I appreciate your site. Only positive current Carona opportunity is the time to work on our trailer.

Did you remove the existing jacks or leave them on?

Greg Zimmerman May 29, 2020 - 6:39 pm

I left them on, no reason to cut them off.

Just finished this upgrade. Glad I did it. Worksperfectly. Easy with all the information and pictures.

Did you run into any clearance issue with the floor drain on the passenger-front side jack mount? I got my plates all welded on then when is when to fold the jacks up the front right side was pressing on the floor drain valve hardware. Since the plates were already welded in place i ended up having to grind out a groove in jack to allow it to sit right when retracted. It was a bit of a bummer. Wondering if anyone else had this issue.

No, the only clearance issues I’ve had are the propane ground clamp, which is easily resolved. I wonder if they welded your plates a little too far back? They should be as far forward as they can go on the angle of the frame.

Greg – on our older Casita (since sold) I purchased two Toyota jacks from the local junk yard, and installed them on the frame by drilling four holes and bolting them on. Looking back, was this a bad idea, possibly weakening the frame? I have a 2020 on order, and want to install the front jacks to stabilize the trailer.
Enjoy your project posts.

Yes it’s not a good idea to drill into the c-channel on the bottom edge. I would use the weld on plates from LHC.

Did you have the hi-lift axle or the regular height axle?

Greg Zimmerman June 29, 2020 - 5:34 pm

hi-lift axle. It’s not recommended to run the scissor jacks with a low axle. I’ll add that to the article.
