Levelling with Scissor Jacks

JJBirrish is one of those members that I always see very good, solid advice coming from. I consider him pretty close to an expert on here as he always replies with facts and logic.

I have not seen him ever flame anyone here, and he didn't flame the OP. Saying what he did was stupid (or silly to be exact) isn't the same as calling the OP stupid.

Well that makes me feel much better. :R

First, he doesn't know what type frame the jacks are used on whether it is a 10" single frame or twin 16" frames so how does he "know" what will happen?

You sir are only atmmpting to create a argument by blowing smoke and mirriors…
First of all I never addressed you or your toy hauler 5er frame…
My reference was to light weight TTs, but most likely would apply to your trailers stacked frame to…


Second, the frame is jacked by 7k plus jacks more than enough to lift the frame safely.


Your frame is jacked by a 7k jacks and mine by a 5k jacks more than enough for both trailers… both mine and my friends are BAL sassier jacks…
I still believe both are poor jacks that lift without stability… I still believe the lift rating they have is a fantasy on their part…


Third, it usually takes under 3" to level a side far from lifting the wheels off the ground or far enough to "bend" a frame.

Not sure what your point is… the op was talking about the frame strength as proven by his corner loft test… I don’t have a problem lifting the trailer by the frame near the axle as suggested by the mfg… but the normal leveling process is so easy I don’t see the point


I see so much BS on forums that new RVers take as truth and it's just not right. Everyday people get the Bigfoot system installed on their 5th wheels and believe me the system is installed on the frame. The only difference between the Bigfoot system is the auto lift function because each of those jacks are just 3,500 lb jacks half the specs of a 7k scissor jack.

Educate me on the Bigfoot and its installation and fitment on TTs or 5ers for that matter… I would be shocked to hear that the Bigfoot is just mounted to the flange of a trailer I beam…

Just to keep new Rvers from taking this as truth or bs maybe you could post a link to the simple bolt or weld to the frame flange installation process for these auto levelers …



I installed the scissor 7,500 lb jacks on my unit and they work very well thank you without any frame bending. Unless your friend JJBirrish is an engineer for RV frames then he should express his "opinions" as opinions and not fact.

The people who installed them and use them have much more information than someone who saw his friends trailer malfunction with stock jacks.

I have installed and used what I have on many trailers, my friend installed his, so tell me what is so different about your unnamed aftermarket jacks…

If you want to discuss your toy hauler triple stacked frame lets do that in a different thread where it might make sense…
