Rear separation fix fail?

We followed the instructions for repairing the rotten floor in our rear bath 75 sovereign given by Inland Andy and got mostly great results. We weren't sure about how high to jack the frame before riveting but we brought it up until the old rivet holes seemed to match everywhere. The variable of course being the top seam where we had cut the quarter panel skin. More on that later. Anyway, after raising the frame and floor we checked inside and out and were elated about the closet doors not binding, the tambour doors of the bathroom cabinets aligning, etc. But the fantastic thing was that the camper door was closing and latching perfectly! So we decided to begin riveting. After a couple evenings of work we had everything riveted and watched as our son lowered the tongue so we could remove the jackstands. Pretty impressive! The tongue did have to lower a little before we could see daylight between the frame and the stands. Removed the stands, brought the tongue back to level, and the outside still looked good. The closet doors are still operating just fine, etc. However, once again, the darn door is off kilter! It is cocked upward in the opening almost as badly as before and the bolt is higher than the strike pocket. So, what to do now? Thought about removing the rivets on top and bottom and see if we can raise it again, but not sure it will work. Maybe the skin just wasn't stretched out all the way until it took on the weight of the frame? I need some pointers here, for sure.

The first picture shows how far the separation was before raising the frame.
Second picture is so you won't ask if I remembered to bolt the floor and channel to the frame. Grate 8 bolts every 4-5 inches all the way around.
Third picture is under the hatch where I had to put a patch over the badly torn edge of the rear skin. You can see the caulking where the skin doesn't come completely down to the bumper plate.

Rear separation fix fail?

In my experience you need to be pretty aggressive with both the frame and the body because the frame will spring back, and the body will have bent down over the years.

After getting the frame right to fit the body, and the body bolted down, I was VERY aggressive with a jack near the rear frame rails of my trailer to straighten body and frame simultaneously.

After straightening I welded reinforcement to the bottom of the frame to keep what I had gained. The frame will really want to bend where it is notched for the axles.

Would that require removing the axles? Maybe I should drop the belly and see if there is any weakness in the frame. I guess having been flexed downward for several years could have caused a crease somewhere. What I have now is very solid. No squeaking in the floor, no movement of the bumper, just not lifted as high as I had intended.

Yea, I did all of this when I was changing out the axles. For my trailer this made a huge difference.

I noticed the word "aggressively". Did you raise it higher than intended so it had room to spring back some after reinforcing, or did it stay where you put it once the welding was done? Asking all these questions because I'm not a welder. I would probably be able to take it to the vocational school welding instructor though.

Can you point me toward the steps you reference from Inland Andy? I'm looking at basically the same problems with my '75 Sovereign. Thanks.

Hillbilly--sorry to barge on your question but we have a somewhat similar issue and the same questions (except we actually have a small crease/bend behind the axle that causes similar "alignment" issues).

What J. Morgan has posted makes total sense to me (at least given the nature of the bending situation on my own trailer which isn't just a little bend might be different for yours). Here is my question--if Hillbilly has fixed his rear end issue and reattached the frame but can't weld reinforcements there "in place" and has to take it somewhere for welding--doesn't the bouncing up and down even further stress his rear end repair job? In other words, if the trailer is prone to returning to its drooping state even in his case where his trailer was just sitting in place, then wouldn't it naturally tend to stress his frame to skin reattachment even more in transit? And when you take it to a welder how do you explain to them exactly what "level" you want the trailer to be (post reinforcement)?

Thanks all

Reason for separation

I have heard about this, in regards to rear bath. Has the cause been identified? Is it metal fatigue over time miles? water damage? a design issue related to the weight of the tub?

Rear separation fix fail?

What gets these trailers is rough roads and worn out axles.

I had my truck hooked to the trailer and I used a big bottle jack about three feet from the bumper of the trailer and I lifted aggressively on each side several times.

My goal was to lift until I had the bow in the sides over the wheels gone.

I was mostly successful.

If I remember I will shoot some pics tomorrow.

This DID straighten the trailer, frame, shell, and everything.

Rear separation fix fail?

If a person didn't have to go far over rough roads the shell wouldn't come back down much I don't think, but I did weld my supports in while it jacked up in the rear.

So far I have kept all I gained, and it is no longer downhill into the bathroom.

I am sure that this procedure is not without risk, but it worked for me. Frankly it is amazing how strong these trailers are when they are buttoned up.

Essentially I was lifting the trailer from the jack to the hitch, and then going inside and jumping...

I am interested to know what it would do with the crease.
