Yes it's odd, that length is going to clash with two cross members, and some reinforcing on the inside at the spring mount. In that case they say to weld onto any other reinforcing you find along the way.
And I suspect I need too add a cross member, but I'm unsure on the spacing requirements there. I may add one that holds the hydraulic winch pump anyway with a short driveshaft to the PTO.
Yeah perhaps, they'll certainly be there in case a weld fails! I don't think big structural steel stuff has any of this when they butt weld sections together. So I feel like the angles are the backup. They're not as wide as the frame and certainly not as tall. There is a fair amount of welding detail, plus they call for qualified persons. That means the welding specifications are defined in those standards.

Hello! What a clean tidy & cool truck you've managed to find! As other's have said, that larger cab is brilliant and something we'd have loved on ours! I wouldn't rush to extend the chassis, because the longer the chassis, the more work the subframe has to do. I built a rear bumper and spare wheel carrier off the back of our chassis that has the spare wheels sitting behind/under the body but carried by the chassis. I've incorporated a forklift style mast so we can lower the rear 'bumper' and wheels down to a more manageable height, because I was told early on that whatever I can do on the truck, my wife needs to be able to do (tip cab, change wheel, drive etc) in case of an accident when remote. We'll be following your build with interest!

That hydraulic pump is massive! Good progress, feels really good getting the FD box off I know, next step is stripping off the redundant wiring, we had about 60kgs worth!

Thank you, and yes I saw your wheel carrying system and was studying with great interest! I plan to either suspend my spare wheel from the chassis, or subframe. I don't like the idea of it hanging on the box itself. I only have one spare, so a little more managable.
I wish I could leave the chassis as it is, but we would be limited to 16ft of box, and I can't make a floorplan work for a growing family of 3+dog. Unless I did a rising roof, and at that point an extension is better. We want 18ft box, with bunk beds at the back and a lowering bed over the dining table at the front. But we're a little way away from making that final plan, so many things to decide on!
You may be looking at the 30kw 3 phase generator, in red? The pump is fairly compact and hangs off the back, I need to move it so it bolts directly to the PTO without a driveshaft big enough to push a car like the generator needed!
That is a serious amount of wiring, I don't think we have that much, I pulled a lot before the box came off. Certainly need to strip lots of air lines for trailer brakes, simplify those circuits as best I can. Maybe move air tanks around, source fuel tanks to hang up front. I'm shooting for 2x200l. Then there is a new battery box since it was inside the rear box, in which I will also install the tilt pump mechanics and perhaps some other mechanical items that can live in a vented box. Oh and remove the auto tyre chains.... oh boy oh boy is this a long road haha.

The teardown phase is just about complete, next step is cutting the frame for the extension. I need to source some material that matches the specs, European standards versus Canada makes that a little challenge but I have the help of a well qualified welder.
I still can't get over how clean this truck is, the brake shoes still have paint on the.
Apart from forgetting to unwind the mega winch, the chassis stripping was easy. Air system including removing trailer brake valves, giant pintle hitch, fuel tank, subframe, wiring, all pulled out. I had to plumb the winch back in to unwind it by manually turning the pump.
Next step is to make some frame stands, get the material and bend it before welding in. Then I'll add the reinforcement and build an extra cross member. This will also hold the air tanks as I'll move those inboard.
That awkward moment when the old van meets the new truck...
What do people do for exhaust exit? I'm going to ditch the stack and don't want to go right to the rear. Where does yours exit? Pics appreciated.

Do you have the MB chassis builder guide? Extending members are bolted not welded in the guide, and in the EU it is not allowed to weld directly to the chassis at.
Our new exhaust exits right down under the air tanks facing down as opposed to the side. I can get a picture later.

I do yes, and I think I've got my head around the process. The bolted in portion is the reinforcing/backup angle parts that extend 500mm past the extension weld.
A picture would be great thank you, I've noticed a lot of commercial box trucks have their exhaust do the same. But I'm thinking if it points out I can keep an eye on exhaust colour and it won't stir up as much dust. I think I'll have it exit just ahead of the rear wheel.

I've always admired the overlanding Mogs we run across on our travels in northern Canada. But speaking of OT, I can't get over this W124 wagon! Is it yours?

You have good taste, Sir!
I have 2 W124 wagons with the incredible OM603 turbo diesels in them. One is our daily driver and the other is a project car.

With apologies to the OP for this sidebar discussion but M-B wagons have always tugged at the heart. We currently drive an S212 wagon and previously a W124 sedan, so the combo is irresistible. OK, back to regular programming...

Here she is, pretty simple stuff, although Ive not had her on really dry dirt roads yet...

Thank you for that, certainly would be the easiest and least intrusive option, I'll see how packaging our storage boxes goes and what room I have. Our boxes will likely be mounted to the subframe so they'll move with the habitat, but I'm not 100% on that yet. Might suspend them from the chassis rails.
