Part II More Failed Frame Welds ...
« on: August 12, 2019, 04:18:41 PM »
Well, we have our rig in a service shop for our yearly maintenance and what did they find... more failed welds on the exterior perimeter lateral supports and some cracking on the axle support brackets. Iíll post some pictures at a later date but we have all been down this road before and it does not come as a surprise.

The good news is that the cracks are just starting and are pretty minor.  Have it booked in at a welding shop in a few weeks. Iím going to request that they reinforce the heck out of it.

At least with other owners posting very similar problems the road to repairing these issues is familiar.

All the best!

Darn. I was hoping your camper was fixed permanently. Good thing you kept checking. Cracking on the axle supports is especially concerning. Maybe take the photos of that repair posted by others to your welder?

So, picked up our rig today and spoke with the tech who performed the work.

1. The axle and the metal axle bracket had developed some cracks and were welded in the shop. Unfortunately this specific shop is not set up for aluminum welding. During their inspection process they noted several failed welds and marked the locations. Nothing really new...

2. Fresh water holding tank, east/ west main supports.  Failed welds on the slide side, door side was ok. Replacement tank supports are failing again. Not surprised that the complete support system is failing.

3. The main cross member supports that run east/ west in front and behind the slide/  wheels, failed. Only on the slide side.

The common denominator is that 80% of my weld failures are on the slide side. My feeling now is that the slide is too heavy for the aluminum frame to maintain itís welds. Iím going to add more structure and reinforce those welds as best that I can. The real PITA is that those main east/ west inside wheel well welds are coated with automotive undercoating. That generally doesnít weld too good! Iím not looking forward to that job.

Also, my recent bottom wall/ frame separation is in the same area as most of the weld failures. Iím starting to think that if you use these trailers on a regular basis and put some decent miles on them the frame canít hold up. Especially on the slide side. My situation is a testament to that, we enjoy our trailer a lot and now must continue to weld a compromised frame. We are not doing any more mods or putting any more money for improvement comforts, that money is being spent on stock aluminum framing and labour.

We donít get any rot but have to contend with always crawling around and looking at all the welds for cracking. If you really use your rig check monthly! If it just weekends your probably going to be ok.

But, regardless of your use check every weld around the slide area and every weld around your fresh tank.

The joy.

I feel your pain....went through a tough time getting my frame fixed, first since I'm under warranty KZ stalled a lot then when I gave up and got it fixed they did reimburse me- after a couple of months and many emails complaining to them.
The other issue was getting a competent welding shop scheduled to do the work.   Places to do expert aluminum repairs are often backed up.
