After building "The Little Big" some time ago i was obsessed with idea of building same truck with trailer in larger scale. And i built some chassis. Still not sure about end result)

Rear tandem axles suspension is similar with LEGO Arocs, only difference - it's more compact. One stud shorter distance between axles, 15 studs total width including dual wheels. Front suspension is 3-link live axle, very close to my "Charged Offroader" front suspension. For keeping front axle width same as rear i used weird 12 pins distance between steering pivots. Steering pivot located inside the wheel, almost best possible choice. 99% proper Ackerman geometry included)

But i have some problems with bodywork.

Front bumper with stairs take a lot of space. And whole front looks very long for me. It looks out of proportions. What i should do? Remake front bumper to make whole construction much shorter? Or move front axle 6-7 studs to front and move engine from that tiny black cover to front of the truck?

Will be nice to hear some suggestions) Thanks for reading anyway.

The front looks really good, but it is indeed too long. I would try to shave off 1 or preferably 2 studs. You might have to compromise on the front fender...

Is the suspension already compressed at the front? There doesn't seem to much space above the wheel for further travel.

It feels like the wheelbase is a bit short, or maybe there should be only 1 axle in the back.

Also, I think the cab might look a bit too long..

Agree, the dimensions don't look 100% right. For e.g.: the width, the wheelbase and the cab overhang.

Otherwise I really like the front, I'll stay up to date

Update. As anyone suggested, i make front as short as possible, keeping front lights. Also, as @Jeroen Ottens noticed - there wasn't enough space for front suspension to work) So, added 0,5 studs more.

Suspension at work. There's same 5x7 frame under middle axle on the other side.

And belly shot. You can see weird rear axles without 5x7 frames used. Reason - using 6.5L axles with stop, so wheels can't pop out from differential with axle. If you pull wheels, you got wheels)

Looks pretty good so far, though the gap around the front wheel is rather ugly. Nice axles, how sturdy are they?

Thanks) I don't like front wheel arch too, trying to make it better. Axles are sturdy enough for manual model of this size. But i sacrificed ability to handle serious torque to keep axles compact.

How sturdy are axles Victor?

Sturdy enough for manual model. Adding 2 beams for bracing will make whole construction suitable for motorized crawler.
