My 31 footer had only 3, IIRC they were 11" long, they were on the front and on the rear curb side. I added one the rear street side. I can't see were it would interfere with anything. I also added tabs outboard on the main frame at the rear hold down area. Thinking about cutting 1/8" plate curved to match the shell and tie the triangle outrigger to the rear main frame.
Good Luck,
Jack

Im not sure what you mean but I have two triangular rear outriggers. I added a piece of angle iron to give a little more support to the rear corners.

Keep going you can do it !!

Well I’m doing some thing about the same. Take a look at my link.
http://www.airforums.com/forums/f36/rear-end-separation-short-term-fix-90941.html

I started just wanting to fix the rear end separation, but discovered that the rear frame was very rusty and had to be replaced. I replaced the back 2 feet on side, and about 4 feet on the other. The frame was so rusty that after I cut the bolts free on one side, I was able to bend the frame back with one hand. I have replaced about 3 out riggers on the rear end, and reinforced one of the floor joists. A couple of years ago, I also replaced the front frame, from the door all they to hitch. For the frame, I have been using galv .25 “ thick, 5” Channel, and painted with por 15. After replacing almost 50 % of the frame so far, its clear why people do the shell off and replace the whole frame. Since I have a family and work that’s not an option for my life at this time. So I will keep fixing piece by piece.
I would cut the main frame rails off at behind the axels were the frame is sagging. Replace it with new .25” 5” channel. Overlap the weld by 12” past the weld with .25” L shaped (angle Iron) and run it all the way past the front of the axles. I would weld one on the inner side of the top and bottom of the c-channel. On the out side of the weld, scab on a piece of flat plate over the weld at least 6” long. You could replace the frame all in one piece, or one side at a time.
The floor joist can be rebuilt with 1/8” angle iron. The outriggers I just bought from Outdoors Mart, it seemed easier than making them.

Now since I just did this, and set my AS on fire, please don’t make the same mistakes I did.

1. Have a spotter while you are welding
2. Have a water hose within reach
3. Clean out all possible flammable stuff, spray foam, old carpent, rotten wood, ect..
4. Spray everything down with water in the area to limit the flame up risk.
5. I should start a Welding Safety Thread…

And a side thought, you might want to check your axles, and the floor in the area that your repairing. If the frame is that rotted, how is the floor?

Good luck, keep chipping away at it. Soon it will be done, or you will have the shell off.

I have been making slow progress on the frame repair. replaced most of the out riggers and in this photo you can see where i have repaired one of the worst sections of the frame. right behind the rear wheel where the frame sagged. http://3.bp.blogspot.com/-lYp3JOyk8k...-23-26_838.jpg

and in this picture I have boxed in the main frame rail

It looks like you are doing a great job. That sure is a lot of work.

Looking good, your welds look much better than mine! What kind of welder are you using? What are you going to finish the frame with? Por 15?

Well my latest welds are getting better but it has been a learning experience. I am using a stick welder. I am going to use POR 15, I have two quarts that I ordered and I am hoping that will be enough. I plan to spray it on.

I kinda urge you to do both brush & spray coating the frame...

Examples:
► The weight-reducing 'lightening' holes in the spars and outriggers will eat a lot of paint when you're trying for even coverage around the stamped edges & voids. Brushing those first will stretch the coverage considerably.
► The underside of every spar, outrigger & ladder frame brushed to be sure you have a thick even coating to better weather aluminum contact.
► Brush every (new?) weld to be sure there's no voids the spray coverage. Beside POR makes a great glue too.. (just kidding)
► Brush the tank(s) retaining bars.
► Brush soak the axle mounting plate top weld line and the circular recesses to seal the gaps.

This is one of those do it first or do it later things... a year later my asphalt driveway still has a wonderful silver mist glaze AND I just went through a pint of POR laying on a mechanics' creeper touching up missed/light spots...

Your right about the glue! I hit my rusty battery stand with por 15 and set it down on the plywood under the AS to dry. there was a few drips that ran down and dried onto the ply wood. I was pretty surprised how much force it took to pull it free. It took pieces of plywood up with it..

Ok most of the major frame repairs are done one major issue remains the tung A frame rails directly below the front of the shell are badly pitted with rust. still feels solid and no through holes but I am thinking while I have easy access maybe I should reinforce some how any suggestions on what would be strongest or weaken the area the least? If I weld U shaped sleeves around the area will I weaken the metal at the welds? here is a photo of the area I am talking about.

Is it rust rusted where that cross member connects to the tongue? Is the rust just on the vertical part of the cross member?

This will be the best time to make this repair, cut out the bad stuff and replace it with fresh steel. You don't want to be pulling your AS down the road in a few years and be wondering if that section is going to break. My welder buddies tell me that a good weld is stronger than the metal around it. So adding more steel should not weaken it. Take your time, I know its hard when you really want to push forward to the next step.
