God let's all throw our money together and take a toy hauler out there. Split expenses. Estimate the cost up front. Pay the up front fee. If it's more we pay more when our up front fee is spent. If it's less, figure out a way to divvy it back up between the people....
Not hard to drive straight through with many people. Drive in shifts baby! I can understand if this year is not feasible, but planning ahead for next year has to be.
