i have 5 wagons, each with different purpose if played wysywyg
One is a deffrolla taxi, with 2 big shootas
One is a static gun platform, with 4 rokkit launchas, lobba, ard case
One has ard case, 4 big shootas, zapp gun, deffrolla and killkannon, used for infantry mopping (either lots of dakka or one big shot

)
One is a basic killkannon platform, 2 big shootas, with deffrolla, designed for cracking open transports and tough units
One with 4 rokkits, kannon , used for transport hunting.
None of these builds is necessarily 'optimal' but i've found them effective enough. I may get another Taxi though..
If you're playing orks, expect to miss, a lot. Use the template options (kannon -frag, killkannon, lobba) if this bothers you, or don't strap as many guns onto your wagon. The payoff when a heavily tooled up wagon gets a good set of rolls can be staggering though

Um.. BW aren't Chimera. You can use the Big Shootas even when the BW is running empty. In think in the previous codex they had bolt on shootas the crew could use, but the big shootas are vehicle weapons, not crew-use ones in this codex.
