SCX10 (RC) → GAZ-66 Camper

I have a SCX10 RC and I want to turn it into a GAZ-66-based ultimate camping vehicle. For me the real problem is, how can I get a 1:10 scale GAZ-66 cabin? I couldn't find it for sale anywhere (if anyone finds it, or something similar, please tell me) so I think I have to resort to making one myself. I only need help on the cabin (for now), the rear-end-part-thing, I can do without any help (I hope ). So, how do I get started on making one?

For people saying I put it in the wrong section:

Notes:

If anyone has any suggestions or criticism, please tell me.

there are loads of models floating around, have one 3d printed and then paint it with a brush.

Shouldn't be a problem

 

Is it worth it to get a premium 3D model this this one? Or will it be fine using a free model like this one or this one?

 

That doesn't really matter unless the model is plain junk like the last one.

I'm not into 3d printing myself, so i don't really know what is good for it and what is not. I bet there are some other around here who might know, try asking around.

 

Turns out that the second one I thought was free, wasn't D:

I'm thinking about using the model from SpinTires, but I have no idea how to get it (I own SpinTires) @BASELKLALIB (you made the MAZ-535 mod, so maybe you can help me?)
