Snoop's Take

The Sulythw Trailer Stabilizer Jacks are designed to enhance the stability of RVs and trailers, particularly during slide-out operations. These adjustable jacks can support up to 1,000 lbs, making them a reliable choice for improving stability in various conditions. Feedback from users highlights their effectiveness, with one satisfied customer stating, "Made a world of difference adding scissor stabilizer jacks," while others appreciate the adjustable height feature, noting, "Jack for ground mount seasonal adjustment." However, some users raised concerns about build quality, with comments like, "This looks like what happens when you crush an aluminum can and then try to get it back into shape," indicating potential weaknesses. Additionally, issues with weight management and the risk of damaging slide mechanisms were mentioned, suggesting that while they can be beneficial, caution is necessary. Overall, despite some mixed reviews, the Sulythw Trailer Stabilizer Jacks are recommended for users seeking enhanced stability in their RV setups, particularly for larger models needing additional support.

What it does well!

Key strengths users can’t stop talking about.
Remote control convenience
It's great when I don't have the help.
Easier operation with minimal manual effort
It’s just a little easier, and you can still do it manually if / when they break.
Effective stabilization in windy conditions
Made a world of difference adding scissor stabilizer jacks. 45mph winds didn't rock and sway the trailer all night.
Effective for stabilizing slide-outs
I got some and they work great.
BINGO - that is precisely what I was looking for.
Adjustable height from 12" to 18"
Jack for ground mount seasonal adjustment.
I’d like to purchase 3-6 manual jacks to help with the 20-45 degree seasonal adjustments.
I currently have it tied up.
Supports up to 1,000 lbs
FWIW, I’m thinking about something similar to the following, but I’ve not yet solved how to adjust t
Durable steel construction
It would take a little creativity to pin this system, but i think you could figure it out.

Where it needs some work!

Areas to watch—feedback on possible improvements.
Poor build quality
Interesting stabilizer jack.
This looks like what happens when you crush an aluminum can and then try to get it back into shape.
Adds unnecessary weight to the camper
I’m *acutely* aware of… and would rather use that weight for other purposes.
Power stabilizers are noisy and under-powered
The power stabilizers have whiny motors that sound under-powered.
Risk of dragging stabilizers on uneven terrain
I can't be the only one that drags my stabilizers once in a while when a campsite entry has a decent slope or otherwise less than ideal entry?
Weak metal construction leading to bending
And even easier to kick until it bends back into place. Weak metal.
Found out mine were for *leveling*, not compensating for a 45° mountain incline.
Jacks are not meant for lifting
Found out the hard way that the stabilizer jacks are not made for lifting… posting this so maybe others can learn from my mistake.
You can bend the frame if you lift with the stabilizers.
Stronger jacks are still not for lifting.
Jacks can bend under stress
You can possibly be thankful they failed - their attachment points on the frame generally aren’t meant to take a huge amount of weight … they may have failed saving yourself frame damage.
I have personally seen bent frames from this.
Jacks feel flexible and do not stabilize effectively
I don’t feel like these work better than the old scissor jacks they feel like they flex in the middle and can still rock side to side.
Though people do rig up some interesting things to dampen the movement.
Risk of damaging slide mechanisms
You can do damage to your slide mechanisms because they put upward pressure on parts that aren’t designed for it.
I have been told universally to not use these. They will damage the slide.
Slides are designed to hold the weight, not be supported from underneath.
Unnecessary for shorter RVs
If you get to 34 or longer you may need a fifth and sixth point of stabilization.

Core Power Plays

The specs and strengths that make it shine.
Experience of upgrading jacks to higher weight ratings
Now my 3500lbs trailer has four upgraded jacks :)

Hidden Hero Hacks

Unexpected tricks and side‑door uses you’ll love.
Discussion on custom modifications for jacks
If I were to create something like this I'd use neo magnets and maybe some studs to keep the jack from shifting.
Basicalle just leaving the mounting plate on trailer, and use a removeable pin instead of a bolt.
Suggestions for creating access points under the trailer
Just crawl under it and cut access hatches, dropping the underbelly entirely is something you don't want to do.
Suggestions for customizing jacks to improve stability
Made a decent difference, but it would be perfect if it was at the ends of the trailer as well.
That's why those strong arms are nice, they do that angle bracing in multiple directions which helps with stability immensely.
It makes the connection to the ground solid instead of relying on leaf springs and tires.

Buyer’s Cheat Sheet

What to check before you click ‘Add to Cart.’
Preference for manual stabilizers over powered ones
I really don't see the point. I kind of don't like the idea of losing camper payload to haul around four more motors.
Learning curve associated with proper use
Oh well I’m still learning as I go.
Advice on using additional leveling tools
For leveling side to side get the stackable blocks for under the tires.
I use the lego blocks to help stabilize side to side.
Advice on stabilizer jack configurations
You can put a jack stand at the hitch, which provides better support than a vehicle.
Advice on using blocks and ramps for stability
I would go buy some 2x6s though. You can get them cheap and home depot or whatever will cut them for you if you want.
Jack it up on the frame and block it if you can.
Discussion on necessity of stabilizers for newbies
Trying to decide if these are necessary. We are newbies.

Cautionary Callouts

Know the pitfalls before they catch you off guard.
Challenges with mounting on less sturdy beams
The only place I can find space in the back is to put it right under my ramp door, and even then the way the bracket is I will probably have to add wood attached to the floor to support it fully.
Use wood block under frame place in the back of trailer.
Preference for scissor jacks for stability
NO wobble or shake. Much better than scissor jacks.
Caution about using stabilizers for lifting weight
They are not meant to bear load or support the weight of the trailer.
Safety concerns when working under unsecured trailers
Not everyone is aware of the danger of working under a load that is not properly secured, and you should be weary telling people to go do things that may get them injured or killed.
