41V15 Frame Break

I looked at my 370FB frame, when I segmented the underbelly. Having a lot of welding experience and manufacturing my own equipment, I think a lot of the failures are a result of their stitch welding approach vs one complete solid weld. I have heard the excuses, that it allows the flex needed. I would counter with, it's the flex that is breaking the stitch welding approach. Only further confirmed, with the fix being a gusset being added.

Then you take the same engineering approach to fasteners through out these RV's and how many are just simply undersized or the wrong thread type applied to the materials. I have a bag full of screws, I have replaced in 3 years.

Now days, engineers are locked in a cubicle and get no real feedback on their design results. I would go further to say, they are too young and lack experience in the sectors they apply their craft. They should be required to spend time repairing and assembling what they design....I know I did that to my Geo-technical PHD I had running my Geotech side....at least I contributed one capable person to an otherwise deaf and arrogant licensed trade...LOL!!!
Is stitch welding cheaper? Is that why manufacturers use that process? If not, then why would they use it? Legit question...I don't know how to weld or what "good" looks like from a methodology perspective. @Campingsxs85 you might also know. Thanks to both of you.

Tell Alliance you want a new rig? Thats ridiculous!
Fix it and trade it in for a better rig. This one may just be a lemon? IMHO 🎩
Best of Luck.
Respectfully, asking for a replacement rig is not the least bit ridiculous. Full timer or part timer, this is a significant manufacturing defect that keeps on presenting. That is exactly when a buyback is appropriate.
 
Stitch welding does have its place in the manufacturing process if it's used correctly but yes RockDr896 is correct they are saving Fab Time and Materials. But I will say I have seen lots of pretty interesting welds. Bad enough where the fabricator/welder misses the joint totally with a cold lapped weld that doesn't bond anyway. It's all about quantity not quality in the mass manufacturing these days!

correct Campingsxs85........with Lippert in the spot light here and maybe Alliance, if they build it to Alliance specs....It only points to a cost savings move for Alliance/Lippert....based on when their liabilities go away. They are building to a warranty and what truck buyers can afford (5th wheels only and leaving out the other options for now). So what happens, when 3 stitch welds, have one or more bad welds? We are saying the same thing, so I am not throwing any shade here. I think this is an example of three nails....but 1 nail failing.

So if I frame a back porch...to save on nail cost....I only put a nail at the top, middle, and bottom nail holes available....If 3 won't hold it, then how would more nails help...(Stitch Welding in my opinion)..... The national builders code and local inspections have responded to the "fly by night" deck builders. If you have a 8" joist, then it needs a solid attachment. The approved joist hanger, makes knowing how many nails are needed. The home owner, inspector, and builder know how many nails are needed. I am thinking a design error exists within the CAD software, or it is a purposeful decision. The reason I started to make my own parts and equipment was not only cost....it was down time. Because the inspection requirement was needed, they had to address the failures of the trades....hence the national building code. The legal protection for the inspection operation by state. So the wild west of the RV industry is agreeing on a standard....owned by 3 major companies.

There is no inspections of any vehicles "on the road today" at the build stage. Despite, it's potential impact on our Federal highways. It is a great example of self policing products and the liabilities of their build mistakes via a warranty and possibly recalls (A Legal thang). I think they "design" to this minimum to "compete on price". If it wasn't for those DIY types, they would have a much smaller market.

The baby boomer bubble is almost at the end (1963). Meaning tradesman or others who have the interest and willing to go through the learning curve to still buy the product are in their 60's. If they don't address the longevity of the RV, then the market is going to change, yet again. Maybe this is why Alliance is moving into Class A and B products by buying a Terex subsidiary.

Anyway, I am just piling on at this point. In welding, there is no real reason to not run a full weld and fasten the entire piece of metal. I think I feel better, having typed my rant. This is nothing our forum can fix, but it is great fire side conversation!! I am also speaking from a perspective, that I think I know what the problem is. So this is just my take....fire away!!

I think you are spot on! I would like to see the industry see them move back to Quality vs Quantity type of mentality. I feel like the industry has let the consumer down on these Frame issues and Many consumers including myself are caught right in the middle of it with a fifth wheel that will be going in yet again for the second frame break with in 1 year. Seems to me as if you had a unit that was 2019ish and older this wasn't even heard of or at least you didn't hear of it as much. This is our 4th camper and by far the biggest POS of them all combined. Never in my wildest dreams thought we would be in this situation. But here we are. Alliance is requesting us to pull this this to Elkhart in Late January for 2 weeks of repairs. Probably another $2,000 in just fuel. This has left a terrible taste in my mouth and unfortunately I am not sure we will own another camper after this one unless some things change in the Industry. We are looking at moving into a Class A but my wife and I haven't really made up our mind yet what we are going to do. We will probably just have to ride this wave for awhile a see how Alliance does on this and go from there.
