You can run VP, but it works better if we support ERC for the effort to bring fuel to the salt for us.
Salt in engine = Spark plug death, among other things. If the intake is anywhere near the front wheel you are going to get salt. If it's on the other side of the engine, you still might get salt.
When Larry said don't worry about a mechanic, what he means is that a dozen people will help you if you need help. Help is no problem, spare parts you can't count on. There might be someone with spares, but within your budget you should bring what you can.
15 runs sounds nice, but what if it breaks on the first run? That's a long drive for nothing. Bring every possible spare part, every tool you own, the kitchen sink . . .
