My first C model in 2020!

An alternate model for 42075 First Responder

Comes with three functions, which are HoG steering, two piston boxer engine under the cab and spring-locked fifth wheel
I have noticed that both 42078 and 42075 use same wheels, so First Responder could be rebuilt into terminal tractor.

It is based on a real machines, that look more-or-less like this one:

Overall look::

This alternate model was designed to haul all trailers compatible with 42078 set, including the A model one.

With trailer from 42078:

And Anthem:

Spring-locked fifth wheel

The fifth wheel is on the same height as in 42078 set:

This model uses 494 out of 513 parts provided in the set and DOES USE spare parts.

I like more than the set  .

Very cool model 

Heyy! I still think we need something like "42078-scale" tag because I see even other set not related anyhow now come in "compatible form"

I have bought third 42078 to make another C model(s) in scale with 42078 ;)

Third??? OMG, this set is going to be sold out way before its retention period  Can't wait so see it anyways!

As for that hard-worker-docker, I have told at RB and will put it here: very authentic model, with functions that preforms amazingly! And "ugly" enough as it should be for that vehicles

Actually, it IS out of production and has been marked as retired at lego.com.

Why was this not the B-model?! Stonking work, Markiewicz! Pairing it with the Mack trailer is genius. 

That is a really amazing C-model!

I really like this C model.
