I just saw this "Lift" setup on another thread. Is this some sort of trailer tongue jack? Any other pictures of this...Brackets, where they are mounted specifically?

Thanks,

Steve

What is the weight limit on a scissor jack? Looks like a neat idea for stability when parked. I would be tempted to raise the jacks all the way, to work under the coach, but there is that pesky weight issue.

When I built my jack setup I couldn't find sissor jacks that would pick the GMC off the ground. I went with the drop leg jacks in the photos below. I use 1 1/2" electric drill to raise and lower them.

Greetings:

I have a "just curious" question regarding the front lift jacks!

From most of what I have read/gathered on the forum, the front cross member is not meant to take any kind of substantial load and should not be used to lift the front end.

Have I read or interrupted those thoughts incorrectly?

Carl.

From the photographs it appears that the scissor jacks attach to the junction of the front cross member (with the holes in it) and
the main frame rails.

Hmmm...

I thought the front cross member is the preferred "jack" point because it lifts both sides evenly.

Jacking from the rails on either side - behind the front wheels - could torque / tweak the frame causing a windshield crack - no ??

Carl,

I really believe the scissor jacks shown on the front frame member are for stability NOT for lifting the coach. I did find one photo by gene that suggests Manny also has electric jacks on his coach.

Steve,

What Carl was referring to was the cross member directly behind the bumper. It is rather light weight and has BIG holes in it.

Some people refer to it as the front cross member as it is the first cross member at the front of the coach just behind the bumper.

The "other" front cross member is the monster that has a slightly curved bottom and two large holes in it located further along the
frame. That's the one I assume you are speaking of.

If you look at the Maintenance Manual you will find the OEM jack hooked to the front bumper where it attaches to the bumper shocks.
This is where you are supposed to jack the GMC up to replace a flat front tire.

Regards,
Rob M.

Thanks Rob - that makes good sense.

Especially because the "jack hook" that I purchased from JimK attaches there...

The second xmember from the front is suitable for lifting the coach the first one which is a c channel is not.
The junction point of the side rails to the cradle I also suitable as is directly under the bogie bracket

Rob,

Thanks for directing my attention to just “where” the jacks were mounted – Went back and took a closer look – Yes, at junction.

Thanks - Carl P.

Carl,

You're welcome.

On our tours we stay at places that have level parking places and usually we can get Double Trouble leveled with just the Power
Level system.

When we first started I would have Helen read the levels (one just above the pantry door for port / starboard and the second is
"around the corner" on the fridge cabinet. I had a hell of a time interpreting what she would say about the level. Then the light
bulb came on and I got her to run the Power Level valves as I read the levels! Much mo betta!

Regards,
Rob

That would be the setup on Chuck Aulger's coach (which has recently been
purchased by Dave DeGraffenreid). Yes, they are trailer jacks. Jim Wagner
also has a similar setup. Chucks ex-coach also has front levelers that
will raise the coach off the ground.

For those who have purchased an iPad, there is a rather neat app called, "Tiltmeter.". It uses the internal sensors to give you a very graphic display of your degree of level. Decide what spot on your coach you would consider a flat level surface and center the bubble.

For those that have not purchased an iPhad, there are numerous equivalents one both Amazon and Play Store. The one I use all the time is GPS Status and Tool Box and it is free.
