If Alenys and Dawn pooled their money they could afford a Big Boss (28,000 credits for a new one)
Big Boss ATV: Size 4, Acc/TS 15/60, Toughness 23 (12), Crew 1+3, Remaining Mods 2; Notes: All-Terrain, MDC Armor.
It can carry 300 lbs of cargo, has a top hatch but no standard weapons and has a range of 300 miles on one electrical charge. I think/thought you guys had a Magical Power Generator but if one that could recharge the ATV would probably be another 5,000 credits and would either need to be on a Lay-Line or use 10 PPE/ISP to generator the power that would recharge the ATV, etc. in about an hour.
Also for Alenys, remember that armor does not stack, so your Dragon Hide in Human form gives you +8 MDC and +3 Toughness. The TW Wizard armor is not as good but does give you access to the darksight and farsight (costing either PPE or ISP to use) powers and so it might be worth it.
You are still strong enough in your Human form that you could use the Mini-Rail gun (or could be mounted onto a vehicle) or Great Chainsword. The great one is two handed of course.
The Eyepatch of Gorth is Magical; cancel One-Eye Hindrance; for 1PP per round, access speak language power and +1 to Persuasion and Streetwise skill checks; Wt. 0lb
