You bet. Glad to help. So a cut here, a paste there, and now the U437 Doka version instructions are done. You may find a Studio generated PDF at Rebrickable for free. Enjoy!

Sorry for my American centric default perspective, but you get the idea.

Just a note of encouragement @MinusAndy; this project is great, and I am excited to see it come to completion. When I built my Spitfire and Typhoon, both took multiple full scale rebuilds. Each time was frustrating and discouraging. In the end I am most proud of these two MOCs because the final build was the result of perfecting all the big and little details. I look forward to seeing this complete, and the final project will be well worth the work it took to get there. Keep it up. I'm happy you kept with the DBG.

I think it needs $$$$ emoji.

I have been waiting for this day!!!!

Sorry to bump this old topic, but after making so many people try to figure out how to build the various U437 MOCs using my less than perfect photo instructions, I rebuilt the Long Wheelbase Dark Bluish Grey U437 in Bricklink Studio and have published more readable instructions. I'll post the LWB Doka cab next. Feel free to download these for free at Rebrickable.com. Enjoy!

I have doubled down on this project as my interest has been reinvigorated in the past weeks. I am working quicker now, and finding small changes to make as I create the studio file of the whole car. Below you can see the final floorpan and the final RWD Engine tub. The floorpan connects to the engine tub by two removable pins, and to either transmission tunnel with four removable pins. Each engine tub connects to a transmission tunnel with six pins, two of which are the red ones below. Additionally, the floorpan connects to the unibody between the doors. Each connection point increases the rigidity of the final car, while allowing for quick modular swaps. I finalized the bodywork for the car last week, so I am now going through the unibody to make sure all the connections are legal, and the build can be replicated by others. Below you can see the first 200 parts of the unibody, and how it fits with the AWD Hybrid Engine tub. The front will connect to the two red pins at the front of the engine tub. As I was starting the manual and sequential transmission tunnel studio files, I found a couple of bracing and strength issues that I think I can improve. I'll try to get to those this week, and post those final versions soon. I am loving this project, particularly as I get near the end. With each passing day, it feels good to be finalizing more and more of it. I missed my deadline of May, but the result seems to be better for it.

Any reason to encourage another Unimog....

Yeah, the issue seemed to resolve itself. I'm not sure what happened, but it was occurring for all my files. I walked away for a couple of days, and it seems to be back to normal. When it happened, I would get the issue in all render qualities, and for all MOCs, and for PNG or PDF renders. I don't know what it was, but I'm happy its gone for the time being.

I posted this in another thread, but here are all three.

Balloon tires roll a little better, so it makes sense to me for a Pullback. 42122 tires would look better though.

Thanks @Jim for another great review. I agree with your assessment about the fenders and overall look of this set. It's great to get new parts in Black, and I'll certainly find use for some of the parts. It's nice to see the clear cylinder parts again, though if I'm honest, I still won't use them in my builds. I do think, because of the source material and the non-technic features like the lights and the "decorations," this set may bring some new builders to the Technic line.

Thanks again @kbalage for another great review. You mentioned the steering is pretty standard, but is this the first set where the steering gear rack is mounted one module behind the steering pivot points? That seems like change worth noting, as this may be the cause for the poor steering circle.

Thanks, and I'm glad you like it. Yeah, I have used this idea in a lot of MOCs. It works well. I only have some of the subbuilds (roof, doors, bed, etc.). It looks like there are some people on Rebrickable who have the whole file. Send them a note, and see if they are able to share it.

Alright, I had a little trouble with the instructions at the end, but I think I figured it out. The 4x4 V-8 Raptor is done. Instructions are at Rebrickable, and sorry about this paywall this time. The MOD keeps all the functions of Set 42126, but adds the following: 4x4 with three differentials V-8 engine Color matched interior Revised rear suspension When I list it that way, it doesn't sound like that much, but the chassis is all redone. The Zetros tires look great, but they do rub a little bit at slight suspension compression and full steering lock. The buggy tires work with no problems. Suspension articulation V-8 Interior changes Final Chassis Instructions available And a video if you care. I have already started on the next MOD of this set, so stay tuned....

I'm never sure where to place Stud.io help questions. Anyone know why my instructions from Bricklink Studio are looking fuzzy? What setting have I inadvertently checked? How do I make it looks like this again?

I'm happy someone turned the Zetros into a Mog: it had to be done. @gyenesvi you did a great job with the design, and the functions works very well with the parts you had available. Thanks for the writeup as well, it was a joy to read your process.

Yeah, I agree, and yeah, the wheel covers look kindof fun. I also like all the Black 2x3 panels. I seem to be using them a lot lately.

I like the wheel arches in black. Seems like a no suspension set based on the ride height.

I think I understand, but while this gives the ability to add another CV joint to the half shaft, I wonder if this will make the differential to 20 tooth gear connection to fragile. Have you tired this setup yet?

There is room for a center differential lock, but the steering axle or frame will need to be modified. Maybe on V2…

@gyenesvi, yes the front differential is held by a frame with balljoint just as @2GodBDGlory shows. My 42126 is in shipping now, so I should be able to finish this soon. The V8 is placed, the 4x4 drivetrain is working, and all the parts for the bodywork should be easy to connect. The V-8 is in, and fits cleanly. The rear axle is a little different. It has a little more clearance, and has a more realistic travel motion. Though the travel distance is the same. Also, everytime I have been under a F-150 the drive shaft is noticeable, so that had to be changed too. I have stared a Studio file, so I'll post instructions for this soon.

I have not yet received the 42126 that I have preordered, but I am already working on the improvements. First up, is the front wheel drive to incorporate 4x4 into the Raptor. I'm not sure I would characterize LEGO as lazy for not adding this feature; it is possible, relatively non-complex, but requires more parts and a complicated structure. It took me a little time to figure something out that meets my expectations and another lateral brace on the bottom swingarms would be better. Getting the rigidity where I wanted it involved making a lot of changes to the frame, but I think I'm happy with what I have. A new differential is added to increase final engine speed. This is mounted into a floating ball joint frame. The rigid axle connects via CV joints to the wheel hubs that are original to 42126. A V8 is added, but is removed to see everything. I have made a new rear axle that is a little cleaner and follows the suspension movement of the F-150 a little better, and I'll show that once the rear frame is done. I am at a loss right now for how to add a working steering wheel. The front is crowded now, but I'll see what I can do.

Great job, and right up my alley. I'm glad I had a little inspiration for you.

Well it has been 6 months since I worked on this project, and it's time to bring it back up. I'm happy to report that Thirdwigg motors has reached an agreement with Octan Racing to provide the power packs for the Ionos Sports Sedan. The engines are final, and I'm slowing working on the rest of the studio file. Below are the Flat 6 Hybrid, V-8, and I-6 power packs.
