You have a completely different situation with it sitting on concrete, but I would still not put jacks under the slide unless your jacks can and do support the trailer. If you have a flat tire, the jacks MUST keep the trailer from dropping, otherwise, the trailer will drop and the slide will not and damage the trailer. JMO.

My recommendation is that you get a supplemental hand jack that can be placed under the outer wall of a slide. Install this jack after the slide is extended and add a reminder to your "prepare to leave" checklist to remove it before pulling in the slide. You might need a board under the slide to distribute the support point force across a larger area than the top of the jack.

I would never put a support under the slide! If you talk to FR they will advise you not to, and I was told if you do and damage occurs it will not be covered. My dealer sells slide supports but when asked he advised against them too. Even a search of the forum shows most people think it is a bad idea, I am not one to just follow the crowd but a sanity check tells me it isnt a good idea and why even consider it.The only time I would think it was acceptable is if you had the frame blocked in a permanent situation then it might be ok. But why? The TT was designed to support itself.

As for tipping over I am wondering what actual conditions would have to exist for that to happen? 60+ MPH winds on an un-stabilized TT, I do not even know if that would do it????? Seems like bad advice to me and after thinking about it, I cannot fathom a feasible situation where it would be blown over other than a hurricane or tornado, which you have a bigger problem anyway and a slide support would not help in any case.

What is your logic or experience in making that statement pmsherman? Am I thinking wrongly?

By the way, do you guys set your levels on the floor or counter top, bumper, what? to call "level"?

Leveled the floor and then adjusted the big level on the front and never used the level on the floor or anything else again. Also leveled front to back and likewise adjusted the big level on the front. Nothing is that critical as to having to have the trailer perfectly level in all directions and spending an excess amount of time getting that last 1/8" on a 2' level. JMO

I use the Andersen 3604 Camper Levelers( ). Once set up properly, they work like a charm. Don’t pay attention to their method of leveling. You’ll need a level for use inside the trailer, a trailer level indicator to mount on the front of the trailer that you can easily see in your truck’s rear view mirror, and a good assistant.

First, disconnect the weight distribution bars then extend your slides. I level my Flagstaff V-Lite by the stove top. Place the level on the stove top to level side to side and determine which side needs to be raised. Place the Andersen levelers under the wheels of the side to be raised. With your assistant in the trailer and you on cell phones, begin pulling the trailer up onto the levelers. Stop when your assistant tells you it’s level. Set parking brake and put truck in Park, and chock the levelers.
Pull in the slides, extend the stabilizers, and extend the slides again. Recheck the level and door swings. If no adjustments need to be made pull in the slides and retract the stabilizers.
Now attach the trailer level indicator (I use the Digital Level Lite so I can see it at night) so that it indicates the trailer is level. Unhitch the trailer and level it front to rear.
Extend stabilizers, then the slides, and you should be pretty darn level.
Now the next time you pull into an RV Park, disconnect the WD bars, look at the level you mounted to determine which side needs to be raised, place the Andersen levelers under the side that needs raising, and pull the trailer as far as needed until level is indicated. Drop stabilizers and extend slides.
All for $100.00 mas o menos.

Jacks down first! Changed over to 6x8 Pressure treated blocks, 16 inches long. Less weight and since have stapled a short piece of yellow rope in a loop to each block. Loop is long enough to prevent having to get under TV when breaking camp. Carry 6 blocks in case I need the extra height on one end of trailer. Two more blocks for tongue jack.

Jacks with 1/4" rise on the slide side, slide, then jacks again. I use external permanently mounted levels. I like to be able to see how much is needed where and by how much at a single glance.

The 1/4" is just MY rig though. Yours WILL vary. It's just what I've found that works for my rigs weight, slide, chocks, and jack config. After I've been trouncing around inside for awhile ground settling puts me about dead level.

Another vote on DO NOT PUT A JACK under your slide! If the winds are so bad that you're concerned about tipping over (hehehe.. ) you're better off to just turtle up.
