I would be very leary of that welding job holding up. Probably would be better to have a proffesional welder do it.

Probably OK in terms of strength. Weld area's decently large. The crossbar undearneath it in the "A" area will help for any upward forces on the ball receiver. I'd be a little concerned about downwards forces from bumps, but it's hard to say without seeing what's inside there and how it's all attached.
How does that work turning left? Do you have to remove the sway bar on the exit ramp, or does it actually have enough clearance?
What's the goal of lengthening it, and why do this vs just a hitch extender?

I believe he mentions tailgate interference as the reason for the mod. As far as a hitch extender, l wondered the same thing. Twenty four inches is quite the extension? Perhaps it was cheaper to make it?

A hitch extender (ball mount) will decrease the capacity of the vehicle receiver, due to increased leverage. This is noted on some of those double receiver adapters that are intended for bike racks. Lengthening the trailer tongue actually decreases the tongue weight on the ball which may affect handling. Apparently the purpose of this mod was to allow the truck tailgate to be opened with the trailer connected. I accomplished that by installing the Ultimate Jack, others use the Jack-e-up.

Hitch extenders reduce capacity and stability. They add slop to the connection. Lengthening the tongue is better, but it does mean you now have a longer trailer, affecting parking and storage, as well as maneuvering in tight spaces.
Tongue weight on the 17’ Casita is such that I’d have no serious concerns about becoming too light on the tongue. I think the actual projection of the extension was only a foot or so, which is a small fraction of the axle-to-coupler length. Reducing tongue weight a bit could actually improve handling by improving front-rear weight distribution on the tow vehicle. It looked like there was a sway bar in use but no WDH.
I’m not a professional metal fabricator, so I can’t comment on whether thus particular tongue extension is adequately engineered. Casita 17’s are known to exhibit some undesirable flex in the frame rails forward of the axle. Wondering if this might make it worse.

Yep. It's a bad idea to make a structural alteration in a critical area like that without the needed welding skills.

I run a longer-than-normal stinger (ball mount) so my F250 superduty supersized tailgate can clear my E21's jack, and its not given me any issues whatsoever.
lets see, its this one,

and is 12.25" long instead of the more normal 7.5"

Our extension was already done to our 13f scamp it was done by a professional welder big difference nr 1. I was skeptical at first but it was designed by an engineer and there is really not much to it!
Just a addition to the tongue and i personally tugged it 20,000 miles and not one problem. it makes it easier to back up and it makes it so the trailer is not right on top of you!
Additionally all we have on the tongue is 1 small gas cylinder and 1 small battery! It feels safe pulling also and i dont notice the trailer drifting around!
The man we purchased it from said Trust Me and he was right!

Be nice to get an update from the guy later on and see how it's working out for him. I'd like the tongue on our trailer to be 6" longer so I could open the tailgate.

My issue wasn't extending the tongue of the trailer, it was the quality of the welding job. Had that guy tried to get a welding job he would have never passed the welding test.

I'm unclear about how the stresses will be transferred between the frame members and the new square HSS extension that he welded on.
After carving up the frame, it does not appear that the web and flanges of the channel were properly re-unified and connected to the HSS.
He attached something under the back end of the new extension beginning at 13:21, but the video never really shows what that is or how it's attached.
Basically, he has increased the lever-arm which will increase the stresses on a frame that's not especially robust to begin with.
If he just needed clearance for the tailgate, I'm not clear that this was a good solution. As Bob mentions above, there are replacement jacks available which would solve that issue.
Overall, I think the design and the execution are questionable and I'd be concerned about the potential for a failure somewhere down the road.

Interesting
Before we comment on ones ability, you might explain how a “professional weld” would be any different than the job this individual did! What would make a professional weld any stronger than welds viewed in the video? If you couldn’t see the quality, then what gives you the right to compare?
Hum........interesting!

I have seen quality welds and plenty of them. I worked in the construction industry for 30 years and have seen thousands of welds. Pipe welds have to be x-rayed to make sure there are no flaws. You could see that the pop and burn style of welding in this video was not proffesional. Even structural welds have to be solid with good penetration and no gaps or burns.

I called out his welding method and was called a "hater" and that I was drunk, seriously!
His method is quite unsound in both bonding and strenght capabilities, period. His wire feed was too fast and power turned up too high resulting in the big, fast arching movements and the snapping and crackle. Yes, I've welded since the 70's and work with a professional steel worker welder with 25 years experience.
Additionally, adding the extra lenght not only adds to frame leverage stress, as noted, but also movement of weight distribution, period.
It's a poor choice to a simple solution, a new jack would have addressed quite adequately.

not the way I would do it but to each his own. Complains on how thin the tongue is and prone to failure. so he compromises it further. he should have run the new tube under the trailer and tied into the frame structure which would have strengthened the structure. should have left the old swaybar mount alone. this is a very critical spot so cutting and scaring the frame there isnt wise. Not running the tube all the way under gives the tongue added leverage on the light weight frame. could just have spent a few bucks and bought another sway ball mount and weld it where you want and just cut off the old ball leaving the base. now he has to get under the frame after every trip and check for structural stability. next he will probably add even more weight on the tongue since there is all this added room. Hope his travels bode well for him.
