No need to "bake" or commit insurance fraud, try to keep these little "insights" for a future book of ignorance you may choose to write while serving your prison sentence. :
The only parts that couldn't be readily cleaned and dried are the insides of the rocker panels, frame rails, torque boxes, and underneath the seat platforms. The solution is simple, after flushing with clean water and allowing a proper amount of time to dry, plug the bottom openings of these parts and fill it full of por 15, when full, unplug and let it drain back into the paint pail. Repeat untill all parts are treated. Access holes can be made with a hole saw and the welded shut after you finish. As for replacing any mechanical parts, evaluate on an individual basis. Wheel bearings don't need to be replaced, only re-packed with fresh grease.
Don't run the engine hoping to evacuate the water like someone previously suggested. This could be the most ignorant thing to do. First, take the spark plugs out and drain the oil. Then crank the engine over to get rid of any water in the cylinders.(this is to avoid blowing your head gaskets, breaking piston rods, or possibly breaking the crankshaft due to a simple principle that water doesn't compress) After this, drain the engine oil. Replace it, run it and it will be fine.
And lastly, try to consult someone "in the know" before attempting damage control without knowing how to correct the situation. If logical thinking isn't your strong suit as with the previous gentlemen discussed, pay someone else to fix the problem. I guarantee you will save money in the long run.
