Shell Off Question

I'm about to separate the shell from the frame on my 67 Safari. I intend to brace the interior with 2x3s, lift the shell and remove frame out from under. My question is; Does anyone know approx. how much a 67 Safari shell weighs? Is this something 4 men can do by hand, or is it best to use 4 bottle jacks from the inside?

use bottle jacks for more control and stability

Think worst case scenarios...
- The shell will want to turn turtle, flip up side down if anyone gets the giggles (just kidding almost yet if the worst should happen..)

- 1x3's are not enough to lift shell using a bottle jack as they will give that 3" up in deflection at the center (I've seen that) when jacking from a foot in from shell with bottle jacks on both sides

- without the jacks there will need to be another one or two men to chase down binding areas to keep from damaging things, the rear tie-down plate was caulk & corrosion welded on mine and the front & rear plates both had hidden rivet slivers that bound up the lift.

-2x3s made a good sleeper to tie into the shell at multiple ribs to spread the weight when the shell is set back down on the cross-supports, like the mud/sleeper plate that rests on a houses concrete foundation that all the following framing attaches to.

- Once you get the shell braced, lifted and resting on blocks above the trailer floor you might try a man-powered lift but then there is no stopping, turning back or setting it down for a minute until its exactly where it needs to be over the cradle you've pre-built for it, unless its directly above the frame not walked away to a remote 'dry-dock' area..

I seem to remember an advertising picture back in the early 70's of several people holding up the shell of an Airstream which would imply the weight is not much but don't recall if it was less inner skin and windows

Minus all liners, insulation, window glass, wiring, hatches, vents & fans, A/C and various covers on the roof it'd sure be easier...

...and an EDIT on above post - should read 2x3's are not enough to lift shell...

Thanks for the replies. I appreciate your input.
The 2x3s are just for interior bracing. For lifting I'm planning on 2x6 or double 2x4s.
The trailer is almost completely gutted at this point. Interior skin, wiring and all. The only thing still there is the two fiberglass end pieces and the windows.
For the sake of safety and the aforementioned "worst case scenario", I suspect I'll probably go with jacks. That means I'll have to build a stand for each corner. The plan is to raise the shell and move the frame out from under, then set the shell down right where it is.
Man, I wish I could do this in a shop with a nice overhead hoist. Oh well........

Before you lift make sure to take accurate measurements of the interior length. Also make sure to take note of where the ribs bolt to the outriggers. I am having an issue I need to move my shell back 1/2 " on my frame and it doesn't want to.

Ok, separation is complete! A little nerve wracking but everything went smoothly. We used a floor jack to get enough elevation to get screwed together 2x4s underneath and up on block towers. I added some extra bracing and it seems quite stable. Waiting on the new axle and doing the needed frame mods now. Hopefully, we'll have the frame back underneath within a month.
