Originally wanted to rebuild 6484, but it had electrics (micromotor+flashing lights) as it's main attraction point, so witheld that due to "no electrics allowed" and went for a model I've seen in a catalogue from 2010 - the firetruck 6752 from Creator series. Image hotlinked from BL, not planning on buying the set.

Functionality from original:

- lifting of the ladder

- extension of the ladder

- rotation of the ladder

- openable doors + interior (though the seating shall become blue like any true Technic set)

Planned additions:

- RWD

- V6

- steering wheel (might include, current technic sets don't even have openable doors...)

Progress:

Scale stays the same, so wheelbase (19s) and width (13s) as well. Rear axle's a bit overengineered, but the 5L axles kept popping out otherwise. The engine is a bit tricky to implement due to the 13s width, but should fit tighly. In the original, none of the rear has any openable doors, but those two round 2x2 tiles can be a perfect place for some gears to actuate ladder functions, with the black levers replaced with gearbox switches. Steering column will be routed to the back, as the ladder would get in the way otherwise. Ladder extension in the original uses a rigid hose, this I will replace with a pulley system. My worry is that the ladder might end up 3s thick , which is not optimal, but right now don't see other way around.

Screenshots below, built irl as well, but renders are better imo. 6752 model from "official sets made in LDD" topic in digital tools subforum. 

 

For today it's all, have a final tomorrow.

Looking good! Never heard of this set before though!

Fun set choice. I remember wanting this set; ended up never getting it though. I also like the modest scale. It will be hard to make it not look too square though.

By the way, I can't not think about set 8280. Be sure to check that out for inspiration :)

Another little thing. With those wide wheels, the front wheel arches will have to be quite large. I don't know if you have the thinner version of the wheels but you might try those too for the front axle, so the wheel arch can be shrunken a little.

8289 might be a good set to check out as well.

Looking good so far, very nice rear axle, btw. Nice to see some set from modern era Creator. 
6484 was my original idea too, as it was one of my dream sets back in the past, when I was browsing through old catalogues.

Thanks very much for warm comments)))

In regards of the 8280, somehow missed it completely while browsing bricklink, though seems that there will be a remake of it as well  

Finally found some time and made small progress:

- Implemented V6

- Some side panelling

- Ladder can be raised and rotated, has been elevated by 1s

For the front wheels, the wheelarches seem good to me, although with small wheels Virtual Pivot Point steering could've been possible (and seems that Lego has used it as well, albeit not in Technic). The ladder is actuated through a mini-LA, seems as if will have to drop the idea of using pulleys for the extension. It is 6s wide as the original, widening to 7s on areas where support is required.

Steering is to be routed rearmost of the turntable, rotation of which will be taken care of through one of the side knobs mentioned in OP, with ascension of the ladder using the one on the other side.

For the front it is indeed hard not to make it a brick on wheels, and "macaroni" pieces look ugly imo. (small concept of the front in spoiler) For the stairs might need to use system parts or half-beams.

The colour- pins will be replaced once model is finished, need to scrap some builds. Apologies for sub-par photos, progress has not been digitised yet.

Double posting, but sorted out the knobs for elevation and rotation as well as HOG.

crappy vid))))

 

I remember getting this set as a child (I’m now eightteen) and my dad said that I would have some time building. I ended up finishing it in three days and I always had fun playing with it. The progress you have now is very good! Is there going to be an opening cabin or grille to reveal the fake engine?

It's a Fire Engine Big Red Brick!
Didn't want to finish it, but it'd be a shame to have yet another unfinished TC entry  
The front doors&seats both on the original and this are in a weird configuration, waaaaay in the back. But it came in handy since there was plenty of space to make the steering wheel work.






Need to steal a few white pieces from my Daihatsu for the roof and rear.

It can sort of be seen through the windows, but emits a pleasant sound when rolling it around.
