yeah, after build, play around with it, maybe modify a bit, then dismantle and keep in original box
i only have a space enough to put 1 set, and i also use big plastic to cover it from dust...
if i want to build a new set, i have to dismantle, keep in box first before build the new set

currently is my B model of 42052 in place...
i have to dismantle the rotor part, the rotor of helicopter take huge place
it seems there will be some holiday after few weeks... may build the A model at the holiday

i'm using the box of 42009, 42030 (looks like my mistake, 42030 box is open front, open side is the technic of this year )
and one small box, i think is 42008...
all my technic parts i keep in these box, 42008 i keep only wheels
you're welcome
any problem for your modification do feel free to share here, i'm sure there's a lot of sifu here willing to help

Many box-huggers and scalpers here   
Also most will just build and display.
Only few modders.

Lego aim is for creativity and to explore/build/mod. The default build is just a guideline. 

You mean you dismantle and keep in original box ? 

I keep full unit. Some put in plastic bags and display on simple rack, ugly but no need clean the dust, just change plastic bag. Some I put into carton boxes and stack it up. Easy to take out and review/mod/test parts. Sometimes idea comes out which can test on other builds.

well, not easy to find, and price not good as well...
but i think this set should be still able to get if u willing to pay for it
anyway, good luck with your finding
42043 mercedes benz arocs...
this box is open side... so i cannot use back to keep my technic

the box have to be big enough for the set if u do not want to dismantle it
for me, i just dismantle it, and keep in the box...

with open front box, it quite like a new set...
just difference are no plastic bag, no empty space, very heavy, and it is used set
helicopter really take big space because of rotor...
i do have a few cheap helicopter diecast, and the rotor give me big trouble, i have to turn to certain angle to fit in my bookshelf

but lego, it is easy... just dismantle the rotor will do
