A hitch like this can be carried in pieces.

Here is the dry weights listed for the 1970 Overlander model. The first number (ex. 4515) is the dry weight of the Airstream. The second number (ex. 450) is tongue weight also a dry weight. The third number (ex. 19) is the ball height.

1970 OVERLANDER DELUXE LY 27 TWIN 4515 450 19
1970 OVERLANDER DELUXE LY 27 DOUBLE 4565 460 19
1970 OVERLANDER INTERNATIONAL LY 27 TWIN 4525 455 19
1970 OVERLANDER INTERNATIONAL LY 27 DOUBLE 4575 465 19

Based on what I see and not knowing the size of your Suburban, 750lbs. would be a better fit. Airstreams like a soft ride

Ball heights

Published ball heights are only valid, when the trailer comes off the production line.

Airstream's are equipped with "torsion" axles, which contain rubber rods for the "cushion".

As time goes on, those rubber rods slowly deteriorate, which lowers the trailer.

Additionally, any give Airstream, will have a different ball height, depending on it's "pay load".

It is possible, assuming good axles, to lower the ball height about 1 1/2 inches from no load to a full load or overload.

Each owner should measure "their" trailer, to determine the "true" ball height that they will be dealing with.

Again, advertized or published ball heights,"are useless", when the trailer is equipped with a "torsion type" axle.

it's truly SAD 2 see folks repeating this INCREDIBLY BRAINLESS mantra...

especially when u cannot define 'soft ride'

or provide ANY supporting info that links 'soft ride to w/d bar rating'...

the reliable evidence suggests HITCHES have nothing to do with soft/hard...

this is blindly repeating gibberish.

it's a carney workers bark designed to get u into the freak show tent.
_______

not only do you NOT know the 'size of the burb,

u don't know the CONDITION of the airstream

or ANY relevant info required to properly recommend a hitch.

a 40 year old trailer probably needs axles,

this is the SINGLE most important factor affecting 'ride quality' for the stream...

next would be tires, then LOADING, tongue weight and general condition of the trailer.

the trailer may have been mod'd and WILL have 40 years of issues to consider.
________

more over the ISSUE mentioned by the op is "heaviness" lifting/carrying the actual hitch.

suggesting different w/d bars only affect WEIGHT of the hitch a few lbs.

monday morning drivel is still drivel.
_______

there are 2 reasonable replies 4 the op...

1. provide a LOT more info about the rig and include some pics...

2. see a competent hitch/towing tech or experience streamer who can LOOK and HELP in person.


cheers

Yep! What I have just posted is probably "INCREDIBLY BRAINLESS mantra...". Thanks for pointing that out.

momszoo2, This is an open forum and take all advice with a grain of salt.

well that's ALL good info, and perhaps a little bit TOO tidy...

IF the tongue is really 500 lbs many would suggest NO w/d is needed.

this is approximately the weight range (500 lbs) where w/d STARTs to become useful or necessary...

depending on the tow vehicle and it's set up (overhang, tires, suspension, gear/loading)

sway control is useful regardless of w/d and sway control can be had withOUT w/d...

here are a couple of related threads...

http://www.airforums.com/forums/f464...-ii-21000.html

http://www.airforums.com/forums/f464...rol-17986.html

there are a LOT of useful threads here on if/when/how/what is needed for w/d OR sway control...

1. post pics
2. take the rig to a scale and get axle loads, and trailer weights.


cheers

Just get a weight distributing anti sway hitch with a 600# to 800# tongue weight rating.

Greetings momszoo2!

My coach, while 8 years older, is quite similar to yours with a factory stated dry weight of 3,940 pounds with an empty hitch weight of 405 pounds. In reality, my coach which was heavily optioned by the original owners had an, as delivered, empty weight of 4,440 pounds with a tongue weight of 550 pounds. When loaded for an extended vacation, the weight of the coach varies between 6,000 and 6,100 pounds and the hitch weight stays fairly constant at 725 to 750 pounds. I do have twin 40 pound Worthington Aluminum LP cylinders on the hitch rather than the more typical 30 pound cylinders.

My usual tow vehicle is a 1999 K2500 Suburban (3/4-ton with automatic four wheel drive). From 1995 when I towed with a 1995 K-1500 Z71 Club Cab pickup with 5.7 liter, until my first long trip with the Suburban in 1998 I towed with 1,000 pound weight distribution bars. During the prior 31 years, the coach had been used extensively and didn't have any popped rivets nor any cracks in the skin (had always been towed by a full-size Mercury or Oldsmobile coupe). Upon my arrival in Boise, Idaho for the WBCCI International Rally, I had a crack in the aluminum over the entry door; and upon further examination found close to two dozen popped rivets on the interior. A knowledgable Airstream hitch installer inspected my hitch and immediately suggested that I go with 600 pound weight distribution bars due to my firmly sprung tow vehicle. After making those repairs, the crack stopped growing and popped rivets became an infrequent experience. The axles on my coach are original, and still have a down angle on the torsion bars but are very near the point where they will have to be replaced.

Particularly if you choose to use a Reese Strait-Line hitch, I would suggest considering 600 pound weight distribution bars. If you aren't familiar with the Resse Strait-Line hitch, the photo below shows the setup on my Argosy Minuet 6.0 Metre when it is towed with my '75 Cadillac Eldorado.



The weight distribution bars in the photo above are the 500 pound bars that the original owner used to tow the Minuet with his 1978 Ford LTD sedan.

Good luck with your investigation!

Kevin

Kevin.

If your rig in the photo is in a straight line, then the sway control arms are way out of adjustment.

The cams should be perfectly seated on the saddles, when the rig is in a straight line.

Perhaps the photo is misleading?

No, the tow vehicle and trailer are not in a straight line as there isn't sufficient length on my short driveway to straighten the two out after making a left turn from the highway.
