What to do, what to do...
Looking for some input about building a kenworth 3-axle dump like the ones we have up here for the highways dept. See the picture below:
I don't have a tonne of free time lately but I have enough to tinker so I thought it would be best to start with a Tamiya kit and go form there. I am wondering which option you guys think would be best before I pull the trigger and order a kit:
1. Grand Hauler - chop off the sleep, add an axle and a dump bed and be one my way. Cab is pretty different from that kenworth though...
2. Knight Hauler - chop off sleeper, extend chassis, add axle and dump bed. I think this will look a little more similiar?
3. Custom chassis build based on one of the above mentioned bodies?
4. Other?
Any other input would be great!!
Basically I don't realllly know where to begin.

Once I've got a selection ill start modelling it all in CAD and design the details
EDIT: Forgot to add that I am also pondering making this a hook lift truck, so I can put whatever style if bed on that I would like in the future.
