I got the WFO into her final position this evening. I was going to build an overengineered cradle and use a pallet jack, but then inspiration hit - if I'm going to use a pallet jack, why not just use pallets to lift it. With a little reinforcing, it worked like a charm, and saved me $100. The forklift company also refunded my charge after the ordeal (and fixed the damage to the lawn too), so the whole move cost me a total of about $25. One of the quotes I got was $1500! Praise God.
This weekend I hope to get the ventilation designed and the parts ordered.
